Transience in growing subgraphs via evolving sets
Amir Dembo, Ruojun Huang, Ben Morris +1
We extend the use of random evolving sets to time-varying conductance models and utilize it to provide tight heat kernel upper bounds. It yields the transience of any uniformly laz…

Stability and instability of Gaussian heat kernel estimates for random walks among time-dependent conductances
Ruojun Huang, Takashi Kumagai
We consider time-dependent random walks among time-dependent conductances. For discrete time random walks, we show that, unlike the time-independent case, two-sided Gaussian heat k…
