Abstract or Description

We study the wave propagation speed problem on fractals that are not post-critically finite. We extend Y. T. Lee’s result on infinite propagation speed to include these fractals. We also obtained a sufficient condition for finite wave propagation speed that depends on the self-similar measure. Heat kernel estimates play a crucial role in these investigations. We apply our results to the classical infinite Bernoulli convolutions and other fractals. This is a joint work with Wei Tang and Yuanyuan Xie.
