Fizeaux (Parc Valrose)

Giovanni Samaey (K. U. Leuven), Thomas Rey (Laboratoire J.A. Dieudonné)

The DATAHYKING Network-wide research and training event will take place in Nice, on the Campus Valrose of Université Côte d'Azur from September 9th, 2024 et September 11th, 2024. It will feature scientific lectures from international researchers, some training sessions and a meeting with the European Union Project Officer.

The event will take place at the 5th floor of the Building Fizeaux, on the beautiful Parc Valrose of the Université Côte d'Azur.

The social dinner will take place Tuesday, September 10 at 7:00 PM at the restaurant Le Galet, located 3 Promenade des Anglais, 06000 Nice, France (directly on the seafront).

9:30 AM → 10:30 AM Coffee: Welcome and introductory words

10:30 AM → 11:30 AM Jingwei Hu: A brief introduction to the Boltzmann equation and its numerical methods 1/4

In this short course, I will give a brief introduction to the Boltzmann equation including its derivation and basic properties. Then I will introduce the deterministic numerical methods, in particular, the Fourier spectral method, for solving the Boltzmann equation. Both the fast implementation and stability/convergence of the method will be discussed.

9:00 AM → 10:30 AM Siddhartha Mishra: Learning Solution operators of PDEs.

Partial Differential Equations (PDEs) are ubiquitous as mathematical models in science and engineering. Numerical methods are the key tools in their study. Yet, despite their considerable success, the underlying high computational cost inhibits the scope and applicability of numerical methods and necessitates the development of alternatives. In this context, machine learning (ML) algorithms are being increasingly used as surrogates for numerical PDE solvers. In this talk, We will focus on a particular class of ML algorithms that aim to learn the solution operator of PDEs from data. The underlying issues will discussed and different architectures presented. In particular, We will present a very recently proposed Foundation Model for PDEs.
