Abstract

Various string theory realizations of three-dimensional gauge theories relate them to gravitational instantons, Nahm equations and monopoles. We use this correspondence to model self-dual gravitational instantons of Dk-type as moduli spaces of singular monopoles, find their twistor spaces and metrics.
