TSVP Talk: "Universality in Eigenvalue/vector Distributions of Random Tensors" by Naoki Sasakura

Eigenvalues/vectors of tensors are a modern concept extending those of matrices. They appear in various non-linear contexts, such as spin glasses, general relativity, artificial intelligence, quantum information theory, string theory, and so on, while the matrix counterpart in linear-contexts. Understanding universal properties across various tensor eigen problems is important, since this assures their wide applicability. I talk about our recent finding of a universality of tensor eigenvalue/vector distributions, which has been achieved by systematically computing them using quantum field theoretical techniques. 

TSVP Talk: "Degenerate PDEs and Their Underlying Sub-Riemannian Structure" by Federica Dragoni

In the talk, I will show how PDEs, which may appear highly degenerate at first glance, become far more regular when interpreted within a different underlying geometry. In particular, I will focus on PDEs related to the so-called Hörmander regularity theory, which is connected to sub-Riemannian geometries such as the Heisenberg group and Carnot groups. The aim is to provide an overview of this theory that is accessible to a broad scientific audience; therefore, I will mostly concentrate on simple yet significant examples.
