Huajie Liu, Shiguang Ma, Jie Qing, Shuhui Zhong

AI总结:

本文在共形几何中引入中间Schouten曲率的p-Laplace方程,利用p-超调和函数与非线性位势理论得到奇异集Hausdorff维数估计和同伦群消失等几何拓扑结果,推广了Schoen-Yau的工作。

摘要:

本文在共形几何中引入了关于中间Schouten曲率的p-Laplace方程。这些p-Laplace方程为研究流形的几何与拓扑提供了更多工具。首先,中间Schouten曲率的正性可推出局部共形平坦流形上Betti数的消失,这是Böchner公式的结果,与Nayatani和Guan-Lin-Wang的工作一致。其次,也是更有趣的一点是,当中间Schouten曲率非负时,这些p-Laplace方程促进了p-超调和函数与非线性位势理论的几何应用。由此得到了奇异集Hausdorff维数的估计以及同伦群的消失,这一工作受到Schoen-Yau工作的启发并对其进行了推广。在后续论文中,我们将给出p-超调和函数在奇异点处渐近行为的结果。

英文摘要:

In this paper we introduce the p-Laplace equations for the intermediate Schouten curvature in conformal geometry. These p-Laplace equations provide more tools for the study of geometry and topology of manifolds. First, the positivity of the intermediate Schouten curvature yields the vanishing of Betti numbers on locally conformally flat manifolds as consequences of the Böchner formula as in the works of Nayatani and Guan-Lin-Wang. Secondly and more interestingly, when the intermediate Schouten curvature is nonnegative, these p-Laplace equations facilitate the geometric applications of p-superharmonic functions and the nonlinear potential theory. This leads to the estimates on Hausdorff dimension of singular sets and vanishing of homotopy groups that is inspired by and extends the work of Schoen-Yau. In the forthcoming paper we will present our results on the asymptotic behavior of p-superharmonic functions at singularities.
