摘要

本文研究旋转域中自由边界恒均值曲率曲面的存在性和唯一性。这些域的边界由图形的旋转产生。根据生成图形的函数的一些条件和脐张量的间隙条件，我们将自由边界 CMC 曲面归类为拓扑盘或环面。此外，我们还构建了一些旋转椭球体中的自由边界 CMC 曲面实例，这些曲面尤其满足我们的间隙条件。

Gap results and existence of free boundary CMC surfaces in rotational domains

In this paper, we work with the existence and uniqueness of free boundary constant mean curvature surfaces in rotational domains. These are domains whose boundary is generated by a rotation of a graph. We classify the free boundary CMC surfaces as topological disks or annulus under some conditions on the function that generates the graph and a gap condition on the umbilicity tensor. Also, we construct some examples of free boundary CMC surfaces in the rotational ellipsoid that, in particular, satisfy our gap condition.
