加权黎曼流形中强凸集的扩张型不等式

Dilation type inequalities for strongly-convex sets in weighted Riemannian manifolds

Hiroshi Tsuji

摘要:

本文考虑了加权黎曼流形上的一个扩张型不等式,它在高维凸几何中被称为Borell引理。通过引入膨胀轮廓,将膨胀型不等式作为等周型不等式来研究,并在加权里奇曲率下界下,利用相应的模型空间的膨胀轮廓来估计膨胀型不等式.我们还探讨了非负加权里奇曲率下的膨胀曲线的比较得出的函数不等式。特别是,我们显示了几个功能不等式有关的各种熵。

英文摘要:

In this paper, we consider a dilation type inequality on a weighted Riemannian manifold, which is classically known as Borell's lemma in high-dimensional convex geometry. We investigate the dilation type inequality as an isoperimetric type inequality by introducing the dilation profile and estimate it by the one for the corresponding model space under lower weighted Ricci curvature bounds. We also explore functional inequalities derived from the comparison of the dilation profiles under the nonnegative weighted Ricci curvature. In particular, we show several functional inequalities related to various entropies.
