具有无穷体积测度的黎曼流形上的内蕴超压缩性

Intrinsic Ultracontractivity on Riemannian Manifolds with Infinite Volume Measures

Feng-Yu Wang

摘要:

通过建立内禀超Poincaré不等式,给出了非紧完备黎曼流形上扩散半群是内禀超压缩的显式条件.这些条件,以及由此产生的一致的上界的固有热核,是尖锐的一些具体的例子。

英文摘要:

By establishing the intrinsic super-Poincaré inequality, some explicit conditions are presented for diffusion semigroups on a non-compact complete Riemannian manifold to be intrinsically ultracontractive. These conditions, as well as the resulting uniform upper bounds on the intrinsic heat kernels, are sharp for some concrete examples.
