Hyper-Kähler quotient construction of BPS monopole moduli spaces
A simple and explicit construction using the hyper-Kählerian quotient is used to obtain some hyper-Kählerian metrics. These constructions then allow an analysis of such global properties of the manifolds as their topology and completeness. They are also used to analyse the metrics on monopole moduli spaces when some of the monopoles become massless. It is also possible to examine singularities and how to resolve them.
