Shing-Tung Yau: Lectures

TITLE: String duality and G2 manifolds

ABSTRACT: In this talk, I will begin by reviewing the mirror construction of G2 manifolds motivated by string duality (Gukov-Zaslow-Yau) and then discuss the physical interpretation of K stability of 3-dimensional Ricci-flat conical metrics (equivalently, Sasaki-Einstein metric and Kahler-Einstein metrics on Fano orbifolds) and how such metrics can be used to construct non-compact G2-manifolds.
