41:33“Filtering'' CFTs at large N: Euclidean Wormholes, Closed Universes, and Black Hole Interiors
This lecture argues that Euclidean wormholes in AdS/CFT arise from erratic N-dependence in large-N CFTs, proposing a filtering procedure for gravitational duals. It examines both external and internal wormhole configurations.
