一类非线性积分微分方程的全局吸引子
Global Attractors for a Class of Non Linear Integro-Differential Equations
摘要
Abstract
In this paper,we adopt a new method to study the initial-boundary value problem as follows:utt-Δu-γΔut-ωΔutt-Δ∫t 0 k(t-τ)ψ(u(τ), Δu(τ))dτ-h(x,t,u, Δu,ut, Δut)ut-g(x,t,u, Δu,ut, Δut)u+f(u)=σ(x),?(x,t)∈Ω×R+and prove the existence of the global at-tractor Λ for a class of nonlinear integro-differential equations in D(A)×D(A),where h is bounded below,the nonlinear term f satisfies a critical growth exponential condition and the inte-gral term satisfies the condition of exponential decay.关键词
