摘要 研究了下列非线性反应扩散方程初边值问题:{ut(x,t)=Δu(x,t)+up(x,t)+a(x)u(x,t),x∈Ω,t>0 u(x,t)=0,x∈Ω,t>0 u(x,0)=u0(x),x∈Ω非负解的整体存在和爆破问题.文章中利用半群方法得到解的整体存在的条件,利用特征函数方法分析了解在有限时刻爆破的条件. This paper studies the global existence and blow-up of the nonnegative solutions to the initial-boundary value problem for the nonlinear reaction-diffusion equation:{ut(x,t)=Δu(x,t)+up(x,t)+a(x)u(x,t),x∈Ω,t0 u(x,t)=0,x∈Ω,t0u(x,0)=u0(x),x∈Ω The method of semigroup was taken to investigate some conditions under which the global solutions of the above nonlinear reaction-diffusion equation exist,and use eigenfunction method to study the blow-up solutions.
