DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IML-SMR/9/">
 Symmetries and locality in perturbative algebraic quantum field theory</a>
 \nby Kasia Rejzner (University of York) as part of Scattering\, microlocal
  analysis and renormalisation\n\n\nAbstract\nPerturbative algebraic quantu
 m field theory (pAQFT) is a rigorous framework for perturbative QFT\, appl
 icable also on curved spacetimes\, which makes heavy use of microlocal ana
 lysis. The key idea is that through constructing extensions of certain dis
 tributions\, one obtains time-ordered products of quantum fields. This bec
 omes more complicated when symmetries are involved\, e.g. in QED\, Yang-Mi
 lls theories and gravity. In this talk I will explain how the idea of loca
 lity and application of homological algebra naturally lead to a constructi
 on known as BV formalism.\n
