内容摘要:
In this talk, we derive local and global Li-Yau type gradient estimates for positive solutions of the CR heat equation on complete noncompact pseudo-Hermitian manifolds. As applications of the gradient estimates, we give a Harnack inequality for positive solutions of the CR heat equation, and then obtain an upper bound estimate for the corresponding heat kernel. This is a joint work with Yibin Ren and Biqiang Zhao.
