TITLE: G2 instantons in twisted M-theory
ABSTRACT: I will discuss a string theory way to study G2 instanton moduli space and explain how to compute the instanton partition function for a certain G2 manifold. An important insight comes from the twisted M-theory on the G2 manifold. Building on the example, I will explain a possibility to extend the story to a large set of conjectural G2 manifolds and a possible connection to 4d N=1 SCFT via geometric engineering. This talk is based on a work with Michele Del Zotto and Yehao Zhou.
