Gradient flows in the geometry of Sinkhorn divergences

2025-03-28

Speaker: Hugo Lavenant (Bocconi Univ., Milan, Italy)

Wasserstein gradient flows define evolution equations in the space of measures which play a fundamental role in PDEs, probability theory, and machine learning. But what happens when entropic optimal transport is used, instead of classical optimal transport defining the Wasserstein geometry?...

The inhomogeneous multispecies PushTASEP and Macdonald polynomials

2025-03-28

Speaker: Arvind Ayyer (Indian Institute of Science, Bangalore, India)

The inhomogeneous multispecies PushTASEP is an interacting particle system with multiple species of particles on a finite ring where the hopping rates are site-dependent. (The homogeneous variant on \( \mathbb Z \) is also known as the Hammersley-Aldous-Diaconis process.) In its simplest...

Nitsche's finite element method for contact problems

2025-03-28

Speaker: Juha Videman (CAMGSD/IST, Univ. Lisboa)

Nitsche's method is a finite element technique, related to discontinuous Galerkin methods which is predates, that uses a weak formulation without Lagrange multipliers to take into account Dirichlet or contact boundary conditions. Although as such it often becomes...
