All Gravitational Instantons From Monopole Moduli Spaces

Abstract

Initial examples of gravitational instantons of every type emerged from the study of monopoles. In this talk we aim to show that in fact all gravitational instantons can be realized as moduli spaces of monopoles (and Yang-Mills instantons).
