Helfrich曲面的一个分类定理

A classification theorem for Helfrich surfaces

James McCoy, Glen Wheeler

摘要:

本文研究了浸没在$\R^3$中的表面的泛函$\SW_{λ_1,λ_2}$,它是Willmore能量、$λ_1$加权的表面积和$λ_2$加权的体积之和.这与零“自发曲率”的Helfrich泛函相吻合。我们的主要结果是一个完整的分类的所有光滑浸入临界点的功能与$λ_1\ge0$和小$L^2$模的tracefree曲率。特别地,我们证明了不存在的临界点的功能,其表面积和封闭体积是积极的加权。

英文摘要:

In this paper we study the functional $\SW_{λ_1,λ_2}$, which is the the sum of the Willmore energy, $λ_1$-weighted surface area, and $λ_2$-weighted volume, for surfaces immersed in $\R^3$. This coincides with the Helfrich functional with zero `spontaneous curvature'. Our main result is a complete classification of all smooth immersed critical points of the functional with $λ_1\ge0$ and small $L^2$ norm of tracefree curvature. In particular we prove the non-existence of critical points of the functional for which the surface area and enclosed volume are positively weighted.
