Lecture 24: Holographic Entanglement Entropy

In this lecture, Prof. Liu discusses how to calculate the entanglement entropy of a boundary system using the AdS gravity. He gives a holographic proof of the strong Sub-additivity conditions of the entanglement entropy, and discusses a simple example.

Lecture 21: Euclidean Correlation Functions: Higher-point Functions

In this lecture, Prof. Liu continues discussion of Euclidean correlation functions by outlining the prescription for higher-point functions, then discusses evaluation of a Wilson loop of a boundary theory using the corresponding AdS string theory.
