活動内容摘要:
Motivated by porous medium equations with randomly perturbed velocity field, this talk considers a class of nonlinear degenerate diffusion equations with nonlinear conservative noise in bounded domains. The existence, uniqueness and L^1-stability of non-negative entropy solutions under the homogeneous Dirichlet boundary condition are proved. The approach combines Kruzhkov's doubling variables technique with a revised strong entropy condition that is automatically satisfied by the solutions of approximate equations. This talk is based on a recent work with Ruoyang Liu and Yuxing Wang.
