Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Friday, 14 February 2025, at 
11:00 at the Institute of Physics Belgrade, lecture hall 360.

The talk entitled:

QFT on Fuzzy AdS Spaces: Classical Limit and Boundary Correlation 
Functions

will be given by Dušan Đorđević (Faculty of Physics Belgrade).

Abstract: 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.
