活动内容摘要:
By means of a variational approach, time-independent a priori estimates for gradients of solutions to linear parabolic equations in some Orlicz spaces near $L^p$ is derived. These are subsequently used to rule out blow-up in a Keller-Segel type parabolic system involving certain diffusion degeneracies of arbitrary strength.
