### Linear programming for hyperbolic surfaces – Bram Petri (IMJ-PRG Sorbonne University)

I will speak about extremal problems in the (spectral) geometry of hyperbolic surfaces and how linear programming methods based on…

### A Feferman Vaught theorem for products of commutative unital rings – Paola D’Aquino (Università degli studi della Campania “Luigi Vanvitelli”)

We axiomatize the class of commutative unital rings which are elementarily equivalent to a non trivial product of commutative unital connected rings, obtaining in this way a converse of the classical result of Feferman and Vaught for the class of…

### Sobolev embedding and distance functions – Francesca Prinari (Università di Pisa)

On a general open set of the euclidean space, we study the relation between the embedding of the homogeneous Sobolev…

First session of Map Seminar devoted to PhD students and Master students.…

### Construction on quasi-periodic nonlinear waves in fluid mechanics – Riccardo Montalto (Università di Milano Statale)

In this talk, I will discuss some recent results on Euler and Navier Stokes equations concerning the construction of quasi-periodic…

### Capacity and torsional rigidity: two measures of spectral stability – Roberto Ognibene (Università di Pisa)

In this talk, I will discuss the behavior of the spectrum of the Laplacian on bounded domains, subject to varying…
