Euclidean Wormholes and Holography

This lecture by the instructor covers the study of Euclidean wormholes and their implications for holography. The presentation delves into the motivation behind studying wormholes, the distinction between Lorentzian and Euclidean geometries, the stability of wormhole solutions, and the microscopic models that can describe such geometries. The lecture also explores the properties of scalar correlators, Wilson loops, and the interaction between quantum field theories. Additionally, it discusses the construction of toy QFT models, the sandwich construction connecting different theories, and the implications of a-parameters in the context of holography.
