DESCRIPTION:Title: <a href="https://researchseminars.org/talk/3cqfs/30/">P
 erturbative algebraic quantum field theory</a>\nby Kasia Rejzner (Universi
 ty of York) as part of Tricontinental Quantum Fundamentals Seminar\n\n\nAb
 stract\nIn this talk\, I will present the motivation and brief history of 
 perturbative algebraic quantum field theory (pAQFT). It has its roots in t
 he axiomatic framework of Haag and Kastler\, but uses the more pragmatical
  approach of perturbative QFT for the construction of models. At the same 
 time\, the methods used in pAQFT are mathematically rigorous\, as renormal
 ization is treated using the Epstein-Glaser approach\, where physical quan
 tities can be constructed without the need of "subtracting infinities".\n
