Survival probability for jump processes in unbounded domains on metric measure spaces
Phanuel Mariano, Jing Wang
We study the large time behavior of the survival probability for symmetric jump processes in unbounded domains with a positive bottom of the spect…

Spectral bounds for exit times on metric measure Dirichlet spaces and applications
Phanuel Mariano, Jing Wang
Assuming the heat kernel on a doubling Dirichlet metric measure space has a sub-Gaussian bound, we prove an asymptotically sharp spectral upper bound on the survival probability of…
