Stochastic lattice systems for climate models


Tropical weather and climate variability consists of numerous circulation and cloud systems that occur on a hierarchy of temporal and spatial scales ranging from the scale of the convective cloud of 1km to 10 km to planetary intraseasonal disturbances such as the Madden Julian oscillation (MJO) and monsoon dynamics. These systems interact nontrivially with each other and with the global dynamics. Unfortunately, despite most recent improvements, state-of-the-art climate models represent very poorly these systems and their mutual interactions and their interactions with global dynamics as well as the rainfall distributions in the tropics. The representation of clouds and rainfall variability in the tropics is still one of the major uncertainties in the climate models used for the IPCC climate projections. The culprit is believed to be the poor representation of clouds and organized convection by the underlying subgrid models used to represent convection and clouds, which are deterministic in nature, are based on the quasi-equilibrium theory, and as such fail to represent the often chaotic variability due to the interactions of various cloud types with each other and with the environment. Instead, we use a stochastic lattice interacting particle system to represents these clouds and associated interactions using observations as a guiding principle. This leads to a better representation of the afore mentioned tropical modes of variability including the MJO and monsoon dynamics.

The overall goal of this workshop is to initiate new and groundbreaking research in algorithm design and mathematical analysis in scientific computing. The focus is directed at the numerical approximation of partial differential equations (PDEs for short), when randomness is involved either in the input data of the modeling equations or in the approximation algorithms themselves.
Rather than a tight focus on a highly specialized, clearly delineated research field, the workshop aims at cross-fertilization of several recently emerged research directions in applied and computational mathematics around the numerical solution of PDEs. This comprises, in particular, mathematically justified paradigms for the design of adaptive algorithms, the recently strongly advanced understanding of randomized and number-theoretic algorithms such as Monte-Carlo (MC), quasi-Monte Carlo (QMC) and Markov Chain MC (MCMC), sparse and high dimensional approximation, tensor-formatted computations, deep neural network approximation and machine learning algorithms.
The workshop will be held in hybrid mode. Given the current covid-19 situation, places for attending in person are limited. If you are interested in attending, please write an email to Michael Feischl (michael.feischl@tuwien.ac.at) to check the current availability. Details on the workshop can be found at this link.

Emergent phenomena correspond to the appearance of large-scale structures from underlying small scale dynamics. Emergence is ubiquitous in nature: formation of blood capillaries, tumour formation, tissue development, erosion patterns in rocks, pedestrian dynamics, opinion formation, herding, formation of gullies,...
Understanding emergent phenomena requires linking small-scale dynamics with large-scale structures. Kinetic theory has been in the recent years successful in achieving this for some biological and social systems. In this workshop we will review recent progress and discuss future challenges.
In this workshop we will honour

Pierre Degond's

60th birthday as one of the pioneers of applications of kinetic theory to biology and social sciences.

An adaptive multiscale bond order dissection ANOVA approach for efficient electronic structure calculations
We present a multi-scale decomposition approach for the efficient approximate calculation of the electronic structure problem for molecules. It is based on a dimension-wise decomposition of the space the underlying Schroedinger equation lives in. This decomposition is similar to the ANOVA-approach (analysis of variance) which is well-known in statistics. It represents the energy as a finite sum of contributions which depend on the positions of single nuclei, of pairs of nuclei, of triples of nuclei, and so on. Under the assumption of locality of electronic wave functions, the higher order terms in this expansion decay rapidly and may therefore be properly truncated. Furthermore, additional terms are eliminated according to the bonding structure of the molecule. This way, only the calculation of the electronic structure of local parts, i.e. small subsystems of size k of the overall system, is necessary to approximate the total ground state energy. This is approximately done by e.g. the HF-approach, DFT, CI, CC or MP2. This decomposition approach is combined with rising the number p of approximation functions in the discretization of the k-sized subsystems. Then, it turns out that a sparse grid-like approach in the parameters k and p results in a very fast and parallel solution procedure which allows to treat huge bio-molecules in decent run time and results in excellent approximations. Furthermore, our new approach can be used in an adaptive sparse-grid fashion which speeds up things even further. This is joint work with J. Hamaekers and R. Chinnamsetty.

Phase separation from biological and social interaction
Mathematical models for demixing of materials have been investigated extensively in the last decades and are nowadays well understood. A related topic that is far less studied are phase separation effects in biology and social systems. New challenges arise from the self-organized separation, emerging from microscopic interactions between individuals of different kinds. Classical examples are spatial cell sorting, lane formation in pedestrian crowds, or segregation on housing markets. In this talk we will discuss the derivation and analysis of mesoscopic and macroscopic phase separation effects and some applications.

The talk is the sixth one in the series "Distinguished PDE Lecture" organized by the Vienna Center for PDEs and the doctoral school "Dissipation and Dispersion in Nonlinear PDEs". Participation is free of charge but registration is required (until 22 March 2019 sending an e-mail to Ms. Khaladj).

Theories of mathematical diffusion. From old to new
We will first present the mathematical theory of Diffusion and Heat Propagation as seen from the classical point of view of Partial Differential Equations. This will allow us to mention concepts of great beauty and relevance in what follows. We will then introduce our favorite topic of Nonlinear Diffusion, embodied in equations like the Porous Medium Equation, and focused on the existence and properties of the very interesting geometrical objects called Free Boundaries. We will complete the presentation with a review of personal work on diffusion equations involving long distance interactions in the form of Fractional Laplacian Operators. This topic has been intensely developed in the last decade and is still in full bloom.

The talk is the fifth one in the series "Distinguished PDE Lecture" organized by the Vienna Center for PDEs and the doctoral school "Dissipation and Dispersion in Nonlinear PDEs". Participation is free of charge but registration is required (until 09 May 2018 sending an e-mail to Ms. Khaladj).

Mysterious Holes in the Sky & A Theory for the Motion of Cloud Edges
A holepunch cloud is a curious and rare atmospheric feature where an aircraft, descending or ascending through a thin cloud layer, leaves behind a growing circular hole of clear air. Observed since the early days of aviation, only in 2011 was this holepunch phenomenon simulated in a full-physics numerical weather model. Although the initiation process has long been explained by ice crystal formation, the continued growth of the hole, even up to an hour after its birth, remained a bit of a fluid dynamical mystery. We begin by excluding some of the "obvious" reasons by tweaking the physics in the numerical simulations (fake weather!). We then attribute the expansion of the hole to the presence of an expanding wavefront. The leading edge of this wave is a front of phase change, where cloudy air is continually evaporated and so expands the hole. Our explanation has led us towards the development of a more general theory for an understanding of how atmospheric waves can evolve the shape of clouds. This work is in collaboration with R Rotunno (NCAR), H Morrison (NCAR), R Walsh (SFU) and H Lynn (SFU).

This talk presents our work on high-performance implementations of matrix-free operator evaluation by cellwise integration on the fly with sum factorization techniques. Our realization is made available through the deal.II finite element library and targets generic weak forms not tied to a specific equation, but with the restriction of quadrilateral and hexahedral meshes. It is embedded into the advanced numerical features of the deal.II library such as high approximation orders, mesh adaptivity, and complex curved meshes within a parallel mesh strategy that can scale to hundreds of thousands of CPUs. A few applications that benefit from these algorithms will be shown. A recent focus of our work has been to establish performance envelopes that characterize the implementation for continuous and discontinuous Galerkin discretizations. Our experiments show that the performance of the matrix-vector product can come within a factor of 1.5 of finite difference stencils on Cartesian meshes, limited by the memory bandwidth of reading the input and writing the output vector, despite the highly flexible nature of the Galerkin method.

Dynamics of pulse patterns in reaction-diffusion systems: a geometric analysis
The study of pattern formation in natural systems is not only an exciting way to apply techniques and develop ideas from the field of dynamical systems and differential equations; the results obtained by mathematical analysis can in turn give insight into the behaviour of these natural systems, creating a fertile feedback between theory (mathematics) and observation/experiment (biology, physics). In this talk, I will explain how to use ideas and techniques from geometric singular perturbation theory to study the existence, stability, and dynamics of pulse solutions (spikes/spots) in the context of general singularly perturbed reaction-diffusion systems. The spatial scale separation induced by this singular perturbation will prove to be pivotal for the analysis. I will give an overview of the current state-of-the-art, and discuss unresolved questions that inspire active research.

Minimizing movements for mean curvature evolution of partitions
In this talk I will discuss some results about the mean curvature evolutions of the bounded space-partitions. Using the minimizing movement method of De Giorgi, I show the existence of a locally time-Holder continuous (weak) motion, defined globally in time. In particular, this solution starting from a partition made by a union of bounded convex sets at a positive distance agrees with the classical mean curvature flow, and the motion is stable with respect to the Hausdorff convergence of the initial partitions. This is a joint work with Giovanni Bellettini.

Propagation of chaos and irreversibility in gas dynamics
I will review various contributions on the fundamental work of Lanford deriving the Boltzmann equation from hard-sphere dynamics in the low density limit. I will focus especially on the assumptions made on the initial data and on how they encode irreversibility. We will see that the impossibility to reverse time in the Boltzmann equation (expressed for instance by Boltzmann's H-theorem) is related to the lack of convergence of higher order marginals on some singular sets.

Mathematics, a key to Climate Change Research
Mathematics in climate research is often thought to be mainly a provider of techniques for solving, e.g., the atmosphere and ocean flow equations. Three examples elucidate that its role is much broader and deeper:

1. Climate modelers often employ reduced forms of "the flow equations" for efficiency. Mathematical analysis allow us to assess regime of validity of such models.
2. Climate is defined as "weather statistics". Yet, climate research focuses on how climate changes in time while a reliable notion of "time dependent statistics" is as yet lacking. Mathematics provides advanced data analysis techniques for time series with non-trivial temporal trends.
3. Climate research, economy, and the social sciences are to generate a scientific basis for informed political decision making. Subtle language barriers often hamper systematic progress in this area. Mathematical formalization helps structuring related discussions and thus enables interdisciplinary research.

Mathematical and numerical modeling of multiphysics problems, with application to the cardiocirculatory system
Cardiovascular diseases unfortunately represent one of the leading causes of death in Western countries. Mathematical models allow the description of the blood motion in the human circulatory system, as well as the interplay between electrical, mechanical and fluid-dynamical processes occurring in the heart. This is a classical environment where multiphysics processes have to be addressed. Appropriate numerical strategies can be devised to allow for an effective description of the fluid in large and medium size arteries, the analysis of physiological and pathological conditions, and the simulation, control and shape optimization of assisted devices or surgical prostheses. This presentation will address some of these issues and a few representative applications of clinical interest.

The talk is the fourth one in the series "Distinguished PDE Lecture" organized by the Vienna Center for PDEs and the doctoral school "Dissipation and Dispersion in Nonlinear PDEs". Participation is free of charge but registration is required (until 23 May 2017 sending an e-mail to Ms. Khaladj).

On structure results for intertwining operators
The intertwining wave operators are basic objects in the scattering theory of a Hamiltonian given as the sum of a Laplacian with a potential. These Hamiltonians are the classical Schroedinger operators of quantum mechanics. For the three dimensional case we will discuss a new representation of the wave operators as superpositions of reflections and translations. In addition, we will also describe some work on random decaying potentials, such as by Bourgain. This is joint work with Marius Beceanu, Albany.

We present several stability results concerning smooth solutions of the compressible Euler and Navier-Stokes system in the class of measure-valued solutions. We show that strong and measure-valued solutions of these systems coincide as soon as the strong solution exists. The question if any measure-valued solution can be generated by a sequence of weak solutions will be also addressed.

Mathematical finance without probability: Pathwise methods, Functional calculus and applications. Motivated by the importance of model uncertainty, there has been a recent surge of interest in mathematical finance for modeling approaches which do not require the specification of a probability measure. A central issue in these approaches is the pathwise construction of integrals with respect to irregular paths of infinite variation. This workshop will discuss the state of the art in non-probabilistic modeling, pathwise integration and applications in finance and uncertainty modeling.

Pedestrian macroscopic models: a game-theoretical approach
Many Individual-based pedestrian models have been proposed in the literature. Some of them rely on the view of pedestrians as rational agents optimizing their trajectory in order to fulfill their goal in a game theoretical framework. In this talk, we propose a macroscopic model based on this idea and show how the search for local equilibria amounts to finding the Nash equilibrium of a suitable game.
An introduction will be given by Christian Schmeiser (WPI c/o Fak. Math. Uni Wien).

Modelling a random rubber band
A rubber band constrained to remain on a manifold evolves by trying to shorten its length, eventually settling on some minimal closed geodesic, or collapsing entirely. It is natural to try to consider a noisy version of such a model where each segment of the band gets pulled in random directions. Trying to build such a model turns out to be surprisingly difficult and generates a number of nice geometric insights, as well as some beautiful algebraic and analytical objects.

The European Summer School in Financial Mathematics aims at bringing together the most talented young researchers in the field, looking at the very young who only just started their PhD studies. The Scientific Committee consists of European leaders and representatives of financial mathematics. We warmly thank them for their encouragement and for accepting to be part of this committee. Their first and main task is to identify the most promising candidates. The successful candidates will be sponsored for their travel and living expenses during the summer school. Further information and an application form can be found here.
For its sixth anniversary, the European Summer School in Financial Mathematics takes place in Vienna. It will be held at the University of Vienna and is part of the Doctoral Program on Dissipation and Dispersion in Nonlinear Partial Differential Equations. Please notice, that in the week after this summer school (2-4 September, 2013), a related summer school on Numerical Methods for Stochastic Differential Equations takes place at the Technical University of Vienna. Further information can be found on the summer school's homepage.
The Summer School is centered around two advanced courses taught by widely recognised experts. We are particularly interested in a well-balanced combination of theoretical and practical input. There will also be some students' seminars where the young participants can get teaching experience and discuss their research.
We hope that the Summer School leads to an active cooperation between the various European institutions. We also hope that the Summer School provides an opportunity to open doors for European students amongst different research centres. Our ambition is also to put the foundations for a more visible European network at the doctoral level in the field of financial mathematics.
This school belongs to the series of the EMS Applied Mathematics schools. We gratefully acknowledge the support of the French Federation of Banks (Federation Bancaire Francaise), INFORM (Scientific Association for Insurance, Financial, and Operational Risk Management) and the European Research Council (ERC).
