QFT on Fuzzy AdS Spaces: Classical Limit and Boundary Correlation Functions
САЖЕТАК:
AdS spacetime, a maximally symmetric solution of Einstein’s equations with a negative cosmological constant, has gained enormous interest because of its space-like boundary and relation with
holographic duality (AdS/CFT). In this talk, we will consider fuzzy AdS space in two and three dimensions and analyze the scalar field propagating on top of this quantum spacetime. We will introduce the
notion of semi-classical states, enabling us to discuss fuzzy generalizations of classical points and boundaries. Establishing the boundary behavior of the scalar field and the classical limit of fuzzy spacetime, we will proceed to analyze quantum fields, obtaining the expression for correlation functions of operators dual to this scalar field at the boundary.
