Optimal matching problems are very classical in computer science, physics and mathematics. In this talk, we will discuss the related rates of convergence of empirical measures associated with n independent random points, whose common distribution is…

Locating Ruelle-Pollicott resonances – Carlangelo Liverani (Università di Roma Tor Vergata)
We study the spectrum of transfer operators associated to various dynamical systems. Our aim is to obtain precise information on discrete spectrum. To this end we propose a unitary approach. We consider various settings where new information can be…
Ottimizzazione Matematica – Sfide e Applicazioni – Andrea Baggio (swissQuant, Zurich)
L’ottimizzazione Matematica suscita notevole interesse nel mondo accademico, sia nell’educazione che nella ricerca, ma qual è l’impatto che ha nel…
Representation theory and configuration spaces – Roberto Pagaria (Università degli Studi di Bologna, Italy)
We introduce the category of finite sets and we study their representations. Then we apply this tool to the study of cohomology of ordered configuration spaces of points on a manifold. In the case of configurations of points on an elliptic curve,…
Machine Learning, fra matematica e vita reale – Jacopo Notarstefano (Nabla)
Essere uno sviluppatore dotato di una laurea in matematica consente di lavorare con quelle tecnologie che richiedono di conoscere un…
On the canonical, fpqc, and finite topologies: the state of the art – Luisa Fiorot (Università di Padova)
This talk is based on joint work with Yves André dedicated to the study of the behaviour of finite coverings of (affine) schemes with regard to two Grothendieck topologies: the fpqc topology and the canonical topology (i.e., the finest topology for…
(Sparse) Linear Algebra at the Extreme Scales – Fabio Durastante (IAC-CNR)
Sparse linear algebra is essential for a wide variety of scientific applications. The availability of highly parallel sparse solvers and preconditioners lies at the core of pretty much all multi-physics and multi-scale simulations. Technology is…
Infinite entropy for transcendental entire functions – Anna Miriam Benini (Università di Parma)
Defining entropy on noncompact metric spaces is a tricky business, since there are several natural and nonequivalent generalizations of the usual notions of entropy for continuous maps on compact spaces. By defining entropy for transcendental maps…
Phase transitions for $\\phi^4_3$ – Trishen Gunaratnam (Université de Genève)
In this talk I will discuss recent results obtained in joint work with Ajay Chandra (Imperial) and Hendrik Weber (Bath) about the large-scale behaviour of the $\phi^4_3$ Euclidean field theory. In particular, I will discuss a surface order large…
A tensor method for semi-supervised learning – Francesco Tudisco (GSSI)
Semi-supervised learning is the problem of finding clusters in a graph or a point-clould dataset where we are given “few” initial input labels. Label Spreading (LS) is a standard technique for this problem, which can be interpreted as a diffusion…
