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
