拟线性抛物方程解的爆破时间下界
Lower bound for blowup time of solution to quasilinearparabolic equation
【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.
【Abstract】 In this paper,the following problem were diseussed ut= Δum+ up- uqin Ω ×( 0,t*),u( x,t) = 0 onΩ ×( 0,t*),u( x,0) = u0( x) in Ω,Where ΩRN was a smooth bounded open domain and N≥3. Obtained the lower bound for the blow- up time of the solution.
