"Recent developments in the AdS/CFT correspondence"

Abstract: The AdS/CFT correspondence asserts the equivalence of string
theory on an anti-de-Sitter background geometry with four dimensional
(super) Yang-Mills theories. In this talk we shall be primarily
interested in relating the spectrum of string excitations to the
anomalous scaling dimensions of composite operators (emerging from
two point functions) in the gauge theory.
Here considerable progress has been made in the last 3 years
on both sides of the correspondence. After reviewing these recent
developments we shall discuss a current project of ours of computing the
AdS_5xS^5 string spectrum in two limits in a light-cone formalism:
The plane-wave (Penrose) and the flat space (large radius) limit and
systematic perturbative corrections thereof.
