Lecture
Euclidean Path Integrals
Description
This lecture covers the concept of Euclidean path integrals, focusing on the formalism and its application in Quantum Field Theory and Perturbation Theory using Feynman diagrams. The instructor explains the path integral representation of the propagator, the time-dependent harmonic oscillator, and the classical action. The lecture also delves into the thermal partition function and the transition from Euclidean to real-time correlation functions.
