Recent Progress on Self-Interacting Processes and Non-Reversible Monte Carlo

Salle W (ENS)

Toutes les informations de la conférence sur la page de l'évènement Anthony Maggs: Large scale dynamics of non-reversible Monte Carlo algorithmsMonte Carlo simulation is a workhorse of the numerical study of physical systems at thermodynamic equilibrium. Non-reversible Monte Carlo algorithms replace the commonly used constraint of detailed balance with global balance. We give examples of situations where this leads to accelerated sampling of physical systems. We argue that the large-scale relaxation of such Event-Chain Monte Carlo methods is linked to the dynamics of the true self-avoiding walk. Francis Lörler: Event […]

Vlad Vicol – On self-similar blowup in 3D incompressible fluids

Jussieu -- salle 15-16-309 4 Place Jussieu, Paris, France

We discuss constraints on hypothetical finite-time (backwards) self-similar blow-up solutions for solutions of incompressible Euler and incompressible Navier-Stokes on R^3. In various situations, we show that the very existence of a smooth similarity profile imposes strong restrictions on the similarity exponent. We also discuss new Liouville-type theorems for the viscous problem.

Automath! Léo Dreyfus-Schmidt: AI tools for the working mathematician

campus de Jussieu (amphi 15)

Recent AI systems are increasingly entering the working environment of mathematicians, offering new ways to explore ideas, search the literature, and formalize arguments. In this talk, we will present a selection of such tools, focusing on their practical use in everyday mathematical work.
