题目:Regularity and asymptotics for the porous medium equation
摘要:Since the pioneering work of Oleinik, Kalashnikov, and Chzou in 1958, the porous medium equation (PME) has been extensively studied. Nevertheless, some fundamental questions remain unresolved. I will provide an overview of the current state of the art regarding the regularity of weak solutions and asymptotics for the Cauchy problem and the Cauchy-Dirichlet problem. The ideas behind the proofs will also be presented.
