重新审视Jelvan-Minkowski公式。具有有界曲率的环境流形中子流形的等周不等式

Jellett-Minkowski's formula revisited. Isoperimetric inequalities for submanifolds in an ambient manifold with bounded curvature

Vicent Gimeno

摘要:

在本文中,我们提供了一个扩展到周围的流形具有极点和径向曲率的旋转对称模型空间的径向截面曲率从上方或下方的浸入子流形的Jelove-Minkowski公式。利用这一推广的Jelvan-Minkowski公式,我们可以集中讨论几个等周问题.更确切地说,是关于任何具有光滑边界的拟紧区域的等周流形的下界,或关于子流形及其变形体积的等周轮廓。在模型空间具有严格递减的径向曲率的特殊情况下,给出了一个Aleksandrov型定理。

英文摘要:

In this paper we provide an extension to the Jellett-Minkowski's formula for immersed submanifolds into ambient manifolds which possesses a pole and radial curvatures bounded from above or below by the radial sectional curvatures of a rotationally symmetric model space. Using this Jellett-Minkowski's generalized formula we can focus on several isoperimetric problems. More precisely, on lower bounds for isoperimetric quotients of any precompact domain with smooth boundary, or on the isoperimetric profile of the submanifold and its modified volume. In the particular case of a model space with strictly decreasing radial curvatures, an Aleksandrov type theorem is provided.
