四维流形上向量丛中的Yang-Mills α流及其应用

The Yang-Mills α-flow in vector bundles over four manifolds and its applications

Min-Chun Hong, Gang Tian, Hao Yin

摘要:

本文在四维黎曼流形上引入了向量丛中Yang-Mills泛函的α-流,并建立了α-流的光滑解的整体存在性.我们证明了α流的解的极限为α \to 1是Yang-Mills流的弱解.利用α-流,我们遵循Sacks和Uhlenbeck的思想,证明了Yang-Mills联络的一些存在性结果,改进了Sedlacek的Yang-Mills泛函的极小化结果.

英文摘要:

In this paper, we introduce an α-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 α-flow with smooth initial value. We prove that the limit of solutions of the α-flow as α\to 1 is a weak solution to the Yang-Mills flow. By an application of the α-flow, we then follow the idea of Sacks and Uhlenbeck to prove some existence results for Yang-Mills connections and improve the minimizing result of the Yang-Mills functional of Sedlacek.
