The optimal matching problem is a classical random variational problem which may be interpreted as an optimal transport problem between…

Per una storia della teoria dei gruppi di Lie: dalle origini a Cartan – Alberto Cogliati (Università di Pisa)
L’odierna teoria dei gruppi e delle algebre di Lie ha la propria origine in una serie di ricerche che il…
An overview on non-matching approximation methods for coupled problems across heterogeneous dimensions – Luca Heltai (SISSA, Trieste)
Many physical problems involving heterogeneous spatial scales, such as the flow-through fractured porous media, the study of fiber-reinforced materials, or…
L-spaces, taut foliations and fibered hyperbolic two-bridge links – Diego Santoro (SNS Pisa)
Heegaard Floer homology was defined by Ozsváth and Szabó in the early 2000s. It consists of a package of invariants…
A regularity result for isoperimetric sets with density – Eleonora Cinti (Università di Bologna)
In this talk, I will present a recent regularity result for isoperimetric sets with densities, under mild H\¨older regularity assumptions…
Diophantine methods and S-unit equations – Samuel Le Fourn (Institut Fourier, Grenoble)
Baker’s method (based on linear forms in logarithms) and Runge’s method (based on the pigeonhole principle) both allow to bound heights of integral points on curves (or even varieties) in certain situations which turn out to be rather different. In…
Braid foliations and Markov theorem – Alice Merz (Università di Pisa)
The theory of braid foliations was developed to study knots and links, as well as surfaces in 3-manifolds. The original…
Introduction to persistent homology – Maria Antonietta Pascali (CNR, Pisa)
The talk will trace the history of persistent homology from its definition to the recent developments, describing the most important properties and theorems of persistent diagrams, with an eye to their applications.…
Semimartingales with jumps, weak Dirichlet processes and path-dependent martingale problems – Francesco Russo (ENSTA-Paris)
In this talk we will revisit the notion of weak Dirichlet process which is the natural extension of semimartingale with…
Grassmann extrapolation of density matrices as a tool to accelerate Born-Oppenheimer molecular dynamics – Federica Pes (Università di Pisa)
Born-Oppenheimer molecular dynamics (BOMD) is a powerful but expensive technique. The main bottleneck in a density functional theory (DFT) BOMD calculation is the solution to the DFT nonlinear equations that requires an iterative procedure that…
