该文证明了非经典反应扩散方程ut-△ut-△u-∫∞^0k(s)△u(t-s)ds+f(x,u)=g(x)在R^3上的全局吸引子的存在性,其中非线性项f(x,u)满足临界条件
We prove the existence of global attractors for the nonclassical diffusion equations with fading memory ut-△ut-△u-∫∞^0k(s)△u(t-s)ds+f(x,u)=g(x) defined on the entire space R^3, where nonlinearity f(x, u) is critical.
