摘要
研究了下面的方程ut=Δum+up-uqinΩ×(0,t*),u(x,t)=0 onΩ×(0,t*),u(x,0)=u0(x)inΩ,这里ΩRN是一个光滑有界的开区域且N≥3.可以得到方程解的爆破时间下界.
In this paper, the following problem were diseussed ut=△um+up-uqinΩ×(0,t*), u(x,t)=0 on Ω×(0,t*),u(x,0)=u0(x) inΩ Where Ω RN was a smooth bounded open domain and N≥3. Obtained the lower bound for the blowup time of the solution.
