报告摘要:The upper and lower bounds of the heat kernel, as well as bounds for the gradient, are derived in the metric measure space (X,d,\mu) having Riemannian curevature dimension condition RCD*(K,N) with $K\in R$ and $N\in[1,\infty)$. For applications,the large time behavior of the heat kernel, the stability of solutions to the heat equation are studied, and the $L^p$ boundedness of the Riesz transform, as well as its local case, are showed.
