A gauge theoretic aspect of parabolic bundles over real curves

Abstract

In this article, we study the gauge theoretic aspects of real and quaternionic parabolic bundles over a real curve $(X,{\sigma }_X)$, where X is a compact Riemann surface and σX is an anti-holomorphic involution. For a fixed real or quaternionic structure on a smooth parabolic bundle, we examine the orbits space of real or quaternionic connection under the appropriate gauge group. The corresponding gauge-theoretic quotients sit inside the real points of the moduli of holomorphic parabolic bundles having a fixed parabolic type on a compact Riemann surface $X$.
