摘要: 考虑弱记忆型经典反应扩散方程解的渐近性态, 在内部和边界非线性项超临界指数增长并满足一定的平衡条件时, 用收缩函数方法和半群理论证明全局吸引子在L2(Ω)×L2μ(R+;L2(Ω))中的存在性.

Abstract: We considered the asymptotic behavior of solutions for the classical reactiondiffusion equation with weak memory. When the internal and boundary nonlinearities adhered to supercritical exponential growth and the equilibrium condition, we proved the existence of a global attractor in L2(Ω)×L2μ(R+;L2(Ω)) by using contractive function method and semigroup theory.

Key words: classical reactiondiffusion equation, nonlinear boundary, weak memory, polynomial growth of arbitrary order
