Effectiveness and strong graph indivisibility

A relational structure is strongly indivisible if for every partition $M = X_0 \sqcup X_1$, the induced substructure on $X_0$ or $X_1$ is isomorphic to $M$. Cameron (1997) showed that a graph is stron...

A new description of the Serre functor for perverse sheaves on P^n

The constructible derived category of P^n is equivalent to the bounded derived category of the principal block of the parabolic category O for sl(n), and to the bounded derived category of a certain s...

On new classes of quantum vertex algebras

We present the construction of a new class of quantum vertex algebras associated with a normalized Yang R-matrix. They are obtained as Yangian deformations of certain S-commutative quantum vertex alge...

Matroids and the integral Hodge conjecture for abelian varieties

Hodge originally formulated his conjecture with integral coefficients. Atiyah and Hirzebruch showed in 1962 that it fails for torsion classes, and later Kollár produced non-torsion counterexamples. Si...

A journey through continued fractions

The continued fraction expansion of a real number is a very efficient tool for finding its best rational approximation. Moreover, continued fractions occur both in many theoretical questions in number...

Asymptotically full measure sets of almost-periodic solutions for the NLS equation

In the study of close to integrable Hamiltonian PDEs, a fundamental question is to understand the behaviour of “typical” solutions. With this in mind it is natural to study the persistence of almost-p...

On moduli of foliations

We will survey different approaches to the moduli theory of foliations before presenting a new KSB approach to constructing moduli spaces of foliations, which yields a proper moduli space for foliatio...

Derivation of Hartree theory for 2D attractive Bose gases

In this talk, I will present recent results on two-dimensional Bose gases with attractive interactions. More precisely, I will discuss the validity of Hartree theory, which states that the ground stat...

PRIN 2022: HIGH ORDER STRUCTURE-PRESERVING SEMI-IMPLICIT SCHEMES FOR HYPERBOLIC EQUATIONS

The closing meeting of the PRIN 2022JH87B4 project "High Order Structure-Preserving Semi-Implicit Schemes for Hyperbolic Equations" will be held in Sapienza University of Rome in November 12-14, 2025....

Entropy-minimizing optimal transport

I will discuss a variant of the classical optimal transport dynamical problem, in which the entropy along the curve is minimized additionally to the kinetic energy.This results into a regularizat...
