Hi! I'm trying to follow the video lectures of the course 'Quantum Field Theory II' by Francois David given at the Perimeter Institute PSI programme, but it would be nice to have some notes or a book which were similar to the lectures. I am especially interested in the part on Wilsonian renormalization. The video lectures are found here Does anyone know which book/lecture notes they used in the course? Or just some that are similar to the treatment in that course?
