Description
Loops in AdS from conformal field theory
"Gauge/gravity duality is often used to compare classical results on the gravity side to leading large-N results in quantum field theory. At higher orders,perturbative loop corrections to the classical gravity results map to 1/Ncorrections to the field theory. We show how crossing symmetry constrains thismapping, and allows a direct conformal field theory computation of loop diagramsin anti-de Sitter space."
