Summary

General coherent systems are defined as pairs (ℰ,S), where ℰ is a rank-n holomorphic vector bundle and S is a vector subspace of H0(ℰρ), ℰρ is the vector bundle induced by ℰ and a representation ρ:GL(n)→GL(W). In this work we will prove a Kobayashi-Hitchin correspondence for a simple general coherent system. This is done using well known gauge theoretic techniques which were developed by Bradlow, Garcia-Prada and Mundet i Riera. The focus of this paper is proving that the stability condition that arises is equivalent to the one defined by Alexander Schmitt.
