讨论了无界区域上非自治广义BBM方程的Cauchy问题,给出了方程解的先验估计,并证明了由方程生成的过程族在H^1(A)弱拓扑下存在一致吸引子.
The Cauchy problems of nonautonomous BBM equations on anunbounded domain are disscussed, the prior estimate of the solutions is obtained,and the existence of uniform attractors for the familie of processes corresponds to the equations in the H1 (A) week topology is proved.
