The directed landscape is a random directed metric on the plane that arises as the scaling limit of classical metric models in the KPZ universality class. In this talk, we will discuss a functional large deviation principle (LDP) for the entire...

We analyse the metastable behaviour of the disordered Curie-Weiss-Potts (DCWP) model subject to a Glauber dynamics. The model is a randomly disordered version of the mean-field q-spin Potts model (CWP), where the interaction coefficients between...

By using Grand Canonical Optimal Transport we provide a counter-example showing that the ground state energy of electrons in an external Coulomb potential is not always a convex function of the number of electrons. This property has been conjectured...

A classical problem in linear algebra is to understand what are the linear subspaces of the space of $m\times n$ matrices such that no matrix in the space has full rank. This problem has connections to theoretical computer science, more precisely...

The starting point for this are clinical studies showing that partial and total meniscectomies lead to prevalence of premature osteoarthritis in knee joints. Accordingly, substantial efforts are being made towards finding adequate regenerative tissue...

We consider the algorithmic problem of the functional decomposition of sparse polynomials. For example, (very) given a very high degree (5∗2 100)(5∗2 100) and very sparse (7 terms) polynomial like f(x)=x(5∗2 100)+15∗x(2 102+2 47)+90∗x(2 101+2 100+2...

While Einstein’s theory of gravity is formulated in a smooth setting, the celebrated singularity theorems of Hawking and Penrose describe many physical situations in which this smoothness must eventually breakdown. In positive-definite signature...

A proper conflict-free colouring of a graph is a (vertex-)colouring with no monochromatic edges such that for every nonisolated vertex v, the neighbourhood N(v) contains a vertex w coloured with a colour not appearing on N(v)-{w}. For a real number h...

I will report the progress we made on the ETH approach for quantum measurements. Here E stands for Events, T stands for Trees and H for histories. I will start with presenting some basics of quantum mechanics, for example, the probabilistic nature of...
