Single point blow-up and regional blow-up of solutions for a degenerate semilinear parabolic equation

摘要：

　　Let q ≥ 0,p ≥ 0,T ≤ +∞,D =(0,a),(D) =0,a,Ω =D×(0,T).This article considers the following degenerate semilinear parabolic initial-boundary value problem,xqut-uxx =xpum,in (0,a)×(0,T),u(0,t)=u(a,t)=0,fort>0,u(x,0)=u0(x),on (D) where a ≥ 0 be constants.We obtained the blow up set and find the conditions of single point blow-up.
