AI总结:

本文研究了柱面的单调性公式,扩展了Volkmann的结果,并应用该结果得到了柱面Willmore能量的Li-Yau型不等式,以及扩展了Fraser-Schoen的最优面积估计至柱面设置。

摘要:

在半空间$\mathbb{R}^3_+$和单位球$\mathbb{B}^3$中,我们建立了柱面的单调性公式,并扩展了Volkmann(Comm. Anal. Geom.24(2016), no.1, 195~221. https://doi.org/10.4310/CAG.2016.v24.n1.a7)为具有自由边界的表面的结果。作为应用,我们获得了柱面的Willmore能量的Li-Yau型不等式,并将Fraser-Schoen在$\mathbb{B}^3$中对最小自由边界表面的最优面积估计(Adv. Math.226(2011), no.5, 4011~4030. https://doi.org/10.1016/j.aim.2010.11.007)扩展到柱面设置,这与Brendle(Ann. Fac. Sci. Toulouse Math. (6)32(2023), no.1, 179~201. https://doi.org/10.5802/afst.1734)证明的另一个最优面积估计不同。

英文摘要:

In this paper, we establish monotonicity formulas for capillary surfaces in the half-space $\mathbb{R}^3_+$ and in the unit ball $\mathbb{B}^3$ and extend the result of Volkmann (Comm. Anal. Geom.24(2016), no.1, 195~221. \href{https://doi.org/10.4310/CAG.2016.v24.n1.a7}{https://doi.org/10.4310/CAG.2016.v24.n1.a7}) for surfaces with free boundary. As applications, we obtain Li-Yau-type inequalities for the Willmore energy of capillary surfaces, and extend Fraser-Schoen's optimal area estimate for minimal free boundary surfaces in $\mathbb{B}^3$ (Adv. Math.226(2011), no.5, 4011~4030. \href{https://doi.org/10.1016/j.aim.2010.11.007}{https://doi.org/10.1016/j.aim.2010.11.007}) to the capillary setting, which is different to another optimal area estimate proved by Brendle (Ann. Fac. Sci. Toulouse Math. (6)32(2023), no.1, 179~201. \href{https://doi.org/10.5802/afst.1734}{https://doi.org/10.5802/afst.1734}).
