摘要:The nonlinear evolutions on locally finite graphs are interesting topics from both pure and applied mathematics. In this talk, we consider two typical problems on a locally finite connected graph. The first one is to study the Bochner formula for the Laplacian operator on a locally finite connected graph. The other one is to obtain global nontrivial nonnegative solution to porous-media equation via the use of Aronson-Benilan argument. We also give a porous-media equation criterion about stochastic completeness of the graph. We want to say that there is not much work in the direction of the study of nonlinear heat equations on locally finite connected graphs.
