Title: BV formalism: from physics to mathematics and back
This talk concerns the BV formalism, or rather its particular version compatible with perturbative algebraic quantum field theory. Its origins are in physics, in the works of Batalin-Vilkovisky, but it has inspired a lot of interesting developments in mathematics. I will explain how it can be used as the guiding principle in mathematical QFT and how it has affected the way one can think about symmetries and observables.
