Yang-Mills联络的能隙,II:任意闭黎曼流形

Energy gap for Yang-Mills connections, II: Arbitrary closed Riemannian manifolds

Paul M. N. Feehan

摘要:

在[arXiv:1412.4114]的这个续篇中,我们证明了主$G$ -丛$P$上的Yang-Mills联络的$L^{d/2}$能隙结果,它是任意的,闭的,黎曼的,维数为$d\geq 2$的光滑流形。我们应用我们的Lojasiewicz-Simon梯度不等式[arXiv:1409.1525,arXiv:1510.03815]以去除先前$L^{d/2}$中的Ricci和黎曼曲率的组合上的正性约束-由于Ger哈特(2010)和之前的$L^\infty$ -能隙结果,由于Bourguignon,Lawson和Simons(1981,1979),以及由于Nakajima的$L^2$ -能隙结果(1987)对于球面上的Yang-Mills联络,$S^d$,但具有任意的黎曼度量。这个版本中的主要更正涉及到将Uhlenbeck(1985)的推论4.3和作者在http://dx.doi.org/10.1016/j.aim.2017.03.023上发表的定理5.1的作用替换为作者在arXiv:1906.03954中的定理1和9的作用。

英文摘要:

In this sequel to [arXiv:1412.4114], we prove an $L^{d/2}$ energy gap result for Yang-Mills connections on principal $G$-bundles, $P$, over arbitrary, closed, Riemannian, smooth manifolds of dimension $d\geq 2$. We apply our version of the Lojasiewicz-Simon gradient inequality [arXiv:1409.1525, arXiv:1510.03815] to remove a positivity constraint on a combination of the Ricci and Riemannian curvatures in a previous $L^{d/2}$-energy gap result due to Gerhardt (2010) and a previous $L^\infty$-energy gap result due to Bourguignon, Lawson, and Simons (1981, 1979), as well as an $L^2$-energy gap result due to Nakajima (1987) for a Yang-Mills connection over the sphere, $S^d$, but with an arbitrary Riemannian metric. The main correction in this version involves replacement of the role of Corollary 4.3 due to Uhlenbeck (1985) and Theorem 5.1 due to the author in the published version of this article at http://dx.doi.org/10.1016/j.aim.2017.03.023 by that of Theorems 1 and 9 due to the author in arXiv:1906.03954.
