Learning seminar on quantum field theory and BV formalism

The aim of this learning seminar is two fold 

1) give a gentle introduction to the basics of quantum field theory (path integral, n-point functions and Wick theorem, Feynman diagrams, gauge fixing and BRST cohomology),

2) present some recent progress related to the BV and BF-BFV formalisms.

We will cover the first part in April and the second one in May.

When?

Every Thursday morning from 10:15 till 12:00 with a 15 minutes break at 11:00
