$\mathbb{H}^3$的$1$ -曲面的半空间定理

Half-space theorems for $1$-surfaces of $\mathbb{H}^3$

G. Pacelli Bessa, Tiarlos Cruz, Leandro F. Pessoa

摘要:

本文研究了浸入在完备黎曼流形$P$中的$1$ -曲面的交问题,其中该流形的Ricci曲率由$-2$下有界.本文首先证明了当$\text{\rm Ric}_{P} > -2$为有界曲率的$1$ -曲面时,曲面浸入$P$的Frankel型定理.在这种情况下,我们也给出了一个标准,以决定是否一个完整的$1$ -曲面是适当的。当实现$1$ -表面之间的距离时,即使$\text{\rm Ric}_{P} \geq -2$。在双曲空间$\mathbb{H}^3$中,我们证明了一类具有有界曲率的完备$1$ -曲面、抛物$1$ -曲面和具有$H<1$的随机完备$H$ -曲面的强半空间定理.作为我们技巧的一个副产品,我们给出了$\mathbb{H}^3.$中$1$ -曲面在无穷远处的极大值原理

英文摘要:

In this paper we investigate the intersection problem for $1$-surfaces immersed in a complete Riemannian three-manifold $P$ with Ricci curvature bounded from below by $-2$. We first prove a Frankel's type theorem for $1$-surfaces with bounded curvature immersed in $P$ when $\text{\rm Ric}_{P} > -2$. In this setting we also give a criterion for deciding whether a complete $1$-surface is proper. A splitting result is established when the distance between the $1$-surfaces is realized, even if $\text{\rm Ric}_{P} \geq -2$. In the hyperbolic space $\mathbb{H}^3$ we show strong half-space theorems for the classes of complete $1$-surfaces with bounded curvature, parabolic $1$-surfaces, and stochastically complete $H$-surfaces with $H<1$. As a by-product of our techniques a Maximum Principle at Infinity is given for $1$-surfaces in $\mathbb{H}^3.$
