Universality and special functions

2026-06-19

Speaker: Thomas Kriecherbauer (Univ. of Bayreuth, Germany)

Universality is the somewhat surprising observation that the behavior of quite different models, sometimes even stemming from different branches of mathematics or physics, may be described by the same class of special functions. An example for this phenomenon that has attracted a good deal...

Incorporating symplectic groupoid multiplication into Poisson integrator methods

2026-06-24

Speaker: Alejandro Cabrera (Uni. Politècnica de Catalunya, Spain)

This talk is based on recent joint work with D. Iglesias and J.C. Marrero. Following O. Cosserat, we first review a general approach to approximate hamiltonian flows in a Poisson manifold. Only the "strict bi-realization" data is used in these approaches, but not the underlying groupoid...

Polaroids

2026-06-24

Speaker: Rui Loja Fernandes (Univ. of Illinois Urbana-Champaign, USA)

How can one simplify a general group action by replacing it with a regular group action, that is, one whose orbits all have the same dimension? In this lecture, I will discuss this problem for proper Lie group actions, as well as its generalization to proper Lie groupoids. I will review some...

From phase separation in heterogeneous media to learning training schemes for image denoising

2026-10-29

Speaker: Irene Fonseca (Carnegie Mellon University, USA)

What do these two themes have in common? Both are treated variationally, both deal with energies of different dimensionalities, concepts of geometric measure theory prevail in both, and higher order penalizations are considered. Will learning training schemes for choosing these...
