摘要

我们证明，具有无限平均退出时间的子漫游无法等轴地、最小地浸入某些积空间的圆柱体、角柱体、圆锥体和楔形中。我们的方法不是基于无穷大时的弱最大原则，因此它允许我们概括以前关于随机完全子曲面不可浸没性的结果。我们还得出了浸入圆柱体的具有小平均曲率的子满足矩塔的估计值。

Mean Exit Times from Submanifolds with Bounded Mean Curvature

We show that submanifolds with infinite mean exit time can not be isometrically and minimally immersed into cylinders, horocylinders, cones, and wedges of some product spaces. Our approach is not based on the weak maximum principle at infinity, and thus it permits us to generalize previous results concerning non-immersibility of stochastically complete submanifolds. We also produce estimates for the complete tower of moments for submanifolds with small mean curvature immersed into cylinders.
