Abstract: S-duality is a non-trivial equivalence of two physical theories. The main aim of the talk is to explain how to mathematically understand S-duality in the simple context of topological string theory, or more precisely, a twisted version of type IIB supergravity theory. Consequences of the new framework include a derivation of the geometric Langlands conjecture in a way different from the famous proposal of Kapustin and Witten. This talk is based on a joint work with Surya Raghavendran.
