Abstract

In this paper we introduce an -flow for the Yang-Mills functional in vector bundles over four dimensional Riemannian manifolds, and establish global existence of a unique smooth solution to the -flow with smooth initial value. We prove that the limit of the solutions of the -flow as is a weak solution to the Yang-Mills flow. By an application of the -flow, we then follow the idea of Sacks and Uhlenbeck [22] to prove some existence results for Yang-Mills connections and improve the minimizing result of the Yang-Mills functional of Sedlacek [26]
