Dirichlet forms and dynamics on fractals

On several types of fractals, it is possible to build a Dirichlet form in a natural way; it is also possible to define a dynamical system and we shall see that the Dirichlet form has a natural relatio...

Stable bundles on Fano and hyper-Kähler manifolds, lezione 3

The aim of this course is to present some recent advances in the theory of stable sheaves on higher dimensional varieties, in particular Fano and hyper-Kähler manifolds. We will start by reviewing the...

Segregated solutions for nonlinear Schrödinger systems with sublinearly coupled nonlinearities

In this talk, we use an enhanced Lyapunov-Schmidt reduction method to study a specific class of nonlinear Schrödinger systems with sublinear coupling terms. We establish the existence of infinitely ma...

Cluster expansion formulas and perfect matchings

Cluster algebras of type A are subalgebras of a field of rational functions in several variables. They are generated by a distinguished set of generators, the cluster variables, which correspond to th...

Radon measure-valued solutions of scalar conservation laws

We present some results for Radon measure-valued solutions of first order scalar conservation laws. In particular we discuss the case in which the singular part of the initial datum is a superposition...

Only 3-points survive!

We study some qualitative properties of the solutions to a segregation limit problem in planar domains. The main goal is to show that, generically, the limit configuration of N competing populations c...

Magnetic curvature and one application to the existence of closed magnetic geodesic

Magnetic systems are the natural toy model for the motion of a charged particle moving on a Riemannian manifold under the influence of a (static) magnetic force. In this talk we introduce a curvature ...

Delta invariants of Fano weighted hypersurfaces

K-stability (or existence of Kähler-Einstein metrics) of explicit Fano varieties has been studied for a long time. Delta invariants (stability thresholds) detect the K-stability of Fano varieties. Mor...

Orthogonal Determinants of Finite Groups

Let \( G \) be a finite group. It is not hard to see that for any representation \( \rho: G \to \mathrm{GL}(V) \) for \( V \) a real vector space, there exists a \( G \)-invariant bilinear form \( \be...

On a series of simple affine VOAs arising from rank one 4D SCFTs

It is known by the works of Adamović and Perše that the affine simple vertex algebras associated with G2 and B3 at level -2 can be conformally embedded into \( L_{-2}(D4). \) In this talk, I will pre...
