在本文中,我们应用的抽象莫尔斯指数公式开发的Tran和周(上的莫尔斯指数与约束:一个抽象的公式。预印本,2020年),以研究几个优化设置的约束。在每一种情况下,我们分类一般索引如何与具有约束的索引相关。此外,对于欧几里得球中的毛细管表面,我们获得了一个指数估计,该估计恢复了Wang和Xia(Math Ann 374(3-4):1845-1882,2019)以及Gou和Xia(J Geom Anal 31(3):2890-2923,2021)作为特殊情况的稳定性结果。通过考虑一族例子,我们证明了这个不等式是尖锐的。此外,我们精确地确定指标的限制,如关键的悬链,在一个球,CMC超曲面的球常数标量曲率的圆柱体和重要的例子。
In this paper,we apply the abstract Morse index formulation developed in Tran and Zhou (On the Morse index with constraints: an abstract formulation. Preprint, 2020) to study several optimization set-ups with constraints. In each case, we classify how the general index is related to the index with a constraint. In addition, for capillary surfaces in a Euclidean ball, we obtain an index estimate which recovers stability results of Wang and Xia (Math Ann 374(3–4):1845–1882, 2019) and Gou and Xia (J Geom Anal 31(3):2890–2923, 2021) as special cases. By considering a family of examples, we show that the inequality is sharp. Furthermore, we precisely determine indices with constraints for important examples such as the critical catenoid, round cylinders in a ball, and CMC hypersurfaces with constant scalar curvature in a sphere.
