Description
In this talk I will give a pedagogical introduction into perturbative algebraic quantum field theory (pAQFT) and briefly sketch the recent results. The pAQFT framework is a mathematically rigorous formalism that allows to prove structural results in quantum field theory (QFT). It combines the axiomatic framework of algebraic QFT with perturbative methods that involve for example expansion into Feynman graphs. On the mathematical side, the pAQFT formalism combines methods of functional analysis, geometry and homological algebra, creating numerous opportunities for interdisciplinary research.
