Euclidean Correlation Functions

This lecture covers the concept of Euclidean correlation functions, transitioning from Euclidean correlators to real-time correlators. The instructor explains the representation of statistical mechanics, periodic paths, and thermal partition functions. The lecture delves into n-point correlators, the Heisenberg picture, and the implementation of real-time derivations. It also discusses the transition from Euclidean to real-time correlators, emphasizing the importance of analyticity and time ordering in the context of thermal n-point functions.
