摘要
利用加强的平坦性条件,证明了带有导数项的反应扩散方程当外力项g(x,t)仅满足平移有界,与时间有关的非线性项f满足临界增长时,指数吸引子的存在性。
The paper established the existence of exponential attractors for a non - autonomous reaction - diffusion equation g (x, t)with distribution derivatives by a method of enhanced flattening properly when nonlinear term f is a polynomial growth of arbitraPy order and external force term translation bounded.
