Abstract
The purpose of this paper is to study the behaviour of sequences of generalised monopoles with a uniform bound on a certain \(L^2\)-norm. We focus on the case that the target hyperKähler manifolds are Swann bundles. In 3-dimensional case, suppose that there exists an open submanifold \(Y'\) such that the hyperKähler potential along the monopoles has a uniform lower bound over \(Y'\). Then we show that there exist convergent subsequences of generalised monopoles over any compact subset of \(Y'\). Under similar assumptions, the same conclusion holds for the generalised harmonic spinors in dimension four.
