THE SEMINAR

THEORY OF DUALITY

DEPARTMENT OF MATHEMATICAL METHODS IN PHYSICS



On the 9th of April 2015, at 10:15 a.m.

Katarzyna Rejzner (Department of Mathematics, University of York)

will give a talk on

"Renormalization without infinities and algebraic structures
in quantum field theory"


Abstract
In this talk I will briefly review the approach to renormalization called causal perturbation theory that avoids dealing with ill-defined objects. This approach started with the seminal paper of Epstein and Glaser (1973) and recently got new interest because of applications to QFT on curved spacetimes. It also allows to uncover some interesting algebraic structures present in perturbative renormalization, like for example Hopf algebras and BV structures.

The seminar takes place on Thursdays from 10:15 a.m. to 12:00 in the room 2.23 of the main building of the Faculty of Physics (the 2nd floor), Pasteur Str. 5, Warszawa.
