平行半球间双曲空间的自由边界等周问题

A Free Boundary Isoperimetric Problem in the Hyperbolic Space between parallel horospheres

Rosa Chaves, Renato Pedrosa, Marcio Silva

摘要:

本文研究了如下等周问题:在三维双曲空间中,求出两平行半球间具有最小边界面积的规定体积区域(不包括半球内边界部分的面积)。通过研究双曲空间中具有常中曲率的旋转曲面的轮廓曲线的性质,将问题归结为对旋转不变区域的研究,并得到了可能的等周解.

英文摘要:

In this work we investigate the following isoperimetric problem: to find the regions of prescribed volume with minimal boundary area between two parallel horospheres in hyperbolic 3-space (the area of the part of the boundary contained in the horospheres is not included). We reduce the problem to the study of rotationally invariant regions and obtain the possible isoperimetric solutions by studying the behaviour of the profile curves of the rotational surfaces with constant mean curvature in the hyperbolic space.
