Klaus Fredenhagen: Local covariance and dynamics in algebraic quantum field theory (Sep 16, 2020)

Abstract: Algebraic quantum field theory provides a conceptually satisfactory and mathematically precise framework for the analysis of structural features of quantum field theory. During the last decades, it has in addition provided a generalization of quantum field theory to generic Lorentzian spacetimes, and, moreover, an elegant reformulation of renormalized perturbative quantum field theory. The principles used there actually determine also a C*-algebraic formulation which is surprisingly rich and leads to some nonperturbative results. In particular, a version of Noether's theorem is obtained. The talk is based on joint work with Detlev Buchholz and on work in progress with Romeo Brunetti, Michael Dütsch and Kasia Rejzner.
