Instantons on multi-Taub-NUT Spaces I: Asymptotic Form and Index Theorem (1608.00018v2)
Published 29 Jul 2016 in math.DG and hep-th
Abstract: We study finite action anti-self-dual Yang-Mills connections on the multi-Taub-NUT space. We establish the curvature and the harmonic spinors decay rates and compute the index of the associated Dirac operator. This is the first in a series of papers proving the completeness of the bow construction of instantons on multi-Taub-NUT spaces and exploring it in detail.
