高负弯曲空间子流形的谱、随机和曲率估计

Spectral, stochastic and curvature estimates for submanifolds of highly negative curved spaces

G. Pacelli Bessa, Stefano Pigola, Alberto G. Setti

摘要:

我们证明了谱,随机和平均曲率估计完全$m$ -子流形$φ\colon M \to N$的$n$ -流形的极$N$的比较等周比$I_{m}$和外半径$r_φ\leq \infty$。我们的证明适用于有界的情况下$r_φ< \infty$,恢复已知的结果,以及为无界的情况下$r_φ=\infty$。在这两种情况下,这些估计的基本成分是比较等周半径的逆$I_{m}^{-1}$在$(0, r_φ)$上的可积性。当$r_φ=\infty$时,如果$N$高度负弯曲,则保证该条件。

英文摘要:

We prove spectral, stochastic and mean curvature estimates for complete $m$-submanifolds $φ\colon M \to N$ of $n$-manifolds with a pole $N$ in terms of the comparison isoperimetric ratio $I_{m}$ and the extrinsic radius $r_φ\leq \infty$. Our proof holds for the bounded case $r_φ< \infty$, recovering the known results, as well as for the unbounded case $r_φ=\infty$. In both cases, the fundamental ingredient in these estimates is the integrability over $(0, r_φ)$ of the inverse $I_{m}^{-1}$ of the comparison isoperimetric radius. When $r_φ=\infty$, this condition is guaranteed if $N$ is highly negatively curved.
