It allows registered users to receive a selection of announcements by email on a daily or weekly basis, and offers the possibility to archive PDF or Powerpoint files, making it available to the scientific community.   [ More information ]


Upcoming Seminars at LPTHE

Monday 3 October 2022, 14:00 at LPENS, L369, 24 rue Lhomond
( 3 lecture mini-course. Each lecture 2 hours. In-person only )
LPTENS-HE (Séminaire commun LPTENS-LPTHE) hep-th
Marcos Mariño ( University of Geneva ) An introduction to resurgence in quantum theory
Abstract: In quantum theory, we often calculate observables approximately by using perturbative series in a small parameter. These series are typically factorially divergent, so we need to make sense of them. The theory of resurgence gives a general framework to do this, and upgrades perturbative series to so- called trans-series, which include exponentially small corrections and make it possible to incorporate non-perturbative physics in a systematic way. Many non-perturbative techniques in quantum theory (like instanton calculus and renormalon physics) are in fact particular examples of this general framework. In these lectures I will give an introduction to resurgence with a focus on applications to quantum theory. After introducing some elementary resurgent technology, I will discuss resurgence in one-dimensional quantum mechanics, and then proceed to discuss what is known about the resurgent structure of quantum field theory.

Susanna Zimmermann ( Laboratoire de Mathématiques d'Orsay, Université Paris-Saclay ) Birational maps of the plane
Abstract: Birational symmetries are among the oldest in literature, starting with the involution at the circle by Apollonius. A birational map is simply a map whose coordinates are quotients of polynomials and that have an inverse map of the same type. The group of birational maps of the plane is very large and has enjoyed attention on and off for about 150 years. In this talk I will give an overview of some recent advances.
