Nonlinear parabolic characterizations of stochastic completeness at infinity on weighted graphs

Davide Bianchi, Bobo Hua, Alberto G. Setti +1

We prove a nonlinear parabolic characterization of stochastic completeness at infinity for weighted graphs. For the filtration equation \[ (\partial_t + ΔΦ)u =0 \] where $\Delta$ is the…
