无界区域上带有记忆项的反应扩散方程全局吸引子的存在性
Global attractor for the reaction-diffusion equation with memory in unbounded domain
摘要
Abstract
The existence of a global attractor is given for the following reaction-diffusion equation with memory in an unbounded domain∞ut-Δu+λu-∫k(s)Δu(t-s)ds+f(u)=g,(x,t)∈Rn×R+,0 where g∈H-1(Rn)and the function f satisfies some suitable increasing conditions.By using the method of non-compactness measure,the existence of global attractors in L2(Rn)×L2μ(R+;H1(Rn))is established.关键词
