报告摘要:We consider the long time behavior for solutions of degenerate diffusion equations with reactions, in both homogenous and spatially periodic environments. For any bounded solution starting from compactly supported initial datum, we show its locally uniform convergence to a steady state by using the zero number argument. For any spreading solution which converges to some positive steady state, we specify its asymptotic profile on the free boundaries by using the corresponding sharp wave.
