3:30 pm (UTC+3) Lecture 1: Tameness and quantum field theory

Abstract: I will discuss the notion of a space of quantum field theories, and explain various approaches to its definition and some of its expected properties. I will then cover joint work with Thomas Grimm and Lorenz Schlechter on tameness of quantum field theories.  This is based on the mathematical concept of o-minimal structures, which has been very powerful for proving finiteness results. Given a QFT or a space of QFTs, we define a corresponding structure, and conjecture in many cases that it is tame (o-minimal).  We also show that Feynman amplitudes at any fixed loop order are tame.

5:00 pm (UTC+3) Lecture 2: Numerical methods for differential geometry

Abstract: State of the art machine learning techniques can be adapted to many problems in scientific and mathematical computation. In this talk, I will explain how this can be done for problems such as finding a numerical approximation to a Ricci flat metric, and discuss results for Calabi-Yau and G2 manifolds as well as exploratory studies on other manifolds.

These lectures are part of the Consortium Distinguished Lecture Series – a joint initiative of the International Center of Mathematical Sciences (ICMS) at IMI – BAS and the Institute of the Mathematical Sciences of the Americas at the University of Miami (IMSA).
