摘要:

设$(M,g)$是闭黎曼$4$ -流形,$E$是$M$上具有结构群$G$的向量丛,其中$G$是紧李群.本文考虑一个新的高阶Yang-Mills-Higgs泛函,其中Higgs场是$Ω^0(\textmd{ad}E)$的一个截面.我们表明,在适当的条件下,梯度流的解决方案不打任何有限时间奇点。在$E$是线丛的情况下,我们能够使用不同的爆破过程,并在\cite{Z1}中获得长时间结果的改进。证明与格林函数的性质有关,这与\cite{Ke,Sa,Z1}中以前的技术有很大不同。

英文摘要:

Let $(M,g)$ be a closed Riemannian $4$-manifold and let $E$ be a vector bundle over $M$ with structure group $G$, where $G$ is a compact Lie group. In this paper, we consider a new higher order Yang--Mills--Higgs functional, in which the Higgs field is a section of $Ω^0(\textmd{ad}E)$. We show that, under suitable conditions, solutions to the gradient flow do not hit any finite time singularities. In the case that $E$ is a line bundle, we are able to use a different blow up procedure and obtain an improvement of the long time result in \cite{Z1}. The proof is rather relevant to the properties of the Green function, which is very different from the previous techniques in \cite{Ke,Sa,Z1}.
