Lecture
This lecture covers topics related to string theory, including AdS/CFT correspondence, critical points in 3D Ising model, and the behavior of gravitons. It discusses the expansion of AdS radius, critical points in the Ising model, and the ordering of coincident points. The lecture also explores stress tensor Ward identities, scalar fields, and the concept of holographic CFTs. It delves into the asymptotic behavior of correlators, the role of D-branes, and the constraints on holographic CFTs. The instructor explains the observables in CFTs, the concept of conformal invariance, and the interactions of different particles in string theory.
