摘要 本文在 [1 ]的基础上 ,通过加权空间的紧性和算子的分解来构造 H2 ( R1)的紧算子 ,证明了推广的 B- BBM方程在 H2 ( R1)中存在一个指数吸引子 . The existence of exponential attractor in H2(R1) is proved for generalized B-BBM equation by constructing compact operators with the compactness of the weighted spaces and the decomposition of operators based on the paper .
