Title What is... Algebraic Quantum Field Theory?
Speaker, Affiliation Stefano Galanda, Dipartimento di matematica - DIMA, Universita di Genova
Date, Time 4 March 2025, 16:30-18:30
Location KO2 F 150
Abstract The Algebraic approach to quantum theories was developed in the end of last century in order to provide a solid mathematical description to the theory of the standard model of particle physics and especially its generalization on curved spacetime backgrounds. Despite its original purpose, the formalism also emerged as a suitable framework for formulating the thermodynamic limit of models in statistical mechanics. The goal of this talk is to provide a gentle introduction to the algebraic approach by first presenting its main motivations and then outlining some of its mathematical foundations. In particular, we will present this approach as an abstract generalization of the mathematical framework of Quantum Mechanics.

Title What is... the Anosov-Katok Construction?
Speaker, Affiliation Baptiste Seraille, ETH
Date, Time 18 March 2025, 16:30-18:30
Location KO2 F 150
Abstract In this talk I will present the Anosov-Katok construction and motivate it by presenting/recalling celebrated results of Poincaré, Birkhoff and Franks. If time permits we will see some recent applications of this construction in the field of symplectic topology.

Title What is... Applied Mathematics in Solar Physics?
Speaker, Affiliation Barbara Palumbo, University of Genoa
Date, Time 25 March 2025, 16:30-18:30
Location KO2 F 150
Abstract In this talk, I will present my research on the application of mathematical techniques to the analysis of data from STIX and HXI, two indirect imagers that measure X-rays emitted by the Sun during solar flares. The presentation will introduce the underlying physical problem, followed by a mathematical formulation that leads to an ill-posed inverse problem. I will discuss the stability of the problem and explore suitable algorithms for its solution. Finally, I will showcase preliminary reconstructions obtained by applying these methods to real observational data.

Title What is... the Manin-Mumford conjecture?
Speaker, Affiliation Tobias Bisang, Universität Basel
Date, Time 1 April 2025, 16:30-18:30
Location KO2 F 150
Abstract This talk is about the Manin-Mumford conjecture, which was proven by M. Raynaud in 1983. The required theory will be presented, including abelian varieties. The first and simplest version of the theorem is as follows: Given a nonzero \(f\in\mathbb{C}[X,Y]\), there exist only finitely many pairs \((q_1,q_2)\in\mathbb{Q}\) with \(f(\mathrm{e}^{2\pi\mathbf{i}q_1},\mathrm{e}^{2\pi\mathbf{i}q_2})=0\), unless there is a very special reason: \(f\) contains a factor of the form \(X^nY^m-\mathrm{e}^{2\pi\mathbf{i}q}\) or \(X^n-Y^m\mathrm{e}^{2\pi\mathbf{i}q}\).
