报告摘要：I will talk about the method (proposed by Jun Kigami)  of defining metrics on twoclasses of fractals (nested fractals and generalized Sierpinski carpets) byusing symmetric self-similar weight functions on its symbolic spaces. We provethat for each such fractal, there is a critical surface for the weights to givea geodesic metric on that fractal. These metrics are crucial in describing heatkernel bounds for time-changed Brownian motions on these fractals viasymmetricself-similar measures. We also illustrate our result b explicit examples. Thisis based on a joint work with Ka-Sing Lau, Hua Qiu and Huo-Jun Ruan.
