活动内容摘要:

By means of a varia欧洲杯买球网tional approach, time-independent a priori estimates for gradients of solutions to linear parabolic equations in  some Or欧洲杯比分licz spaces near $L^p$ is derived. These are subsequently used to rule out blow-up in a Keller-Segel type parabolic syst欧洲杯买球网em involving certain diffusion degeneracies of arbitrary strength.
