摘要
本文讨论了离散化方程的惯性流形,证明了在h充分小且算子 A满足谱间隔条件下,该方程存在一个惯性流形 是惯性映射的不动点.与现有文献 [1,2]不同,我们仅假设主算子A是解析半群无穷小生成元且有紧豫解式,不需要A是自伴的假设.
In this paper the existence of the inertial is the fixed point of the inertial map, is proved Under the assumption that h is small enough and the spectral gap conditions are satisfied for the time-discrete equation F(un). It is different from the other works [1,2] that the capter operator A in this paper is only an infinitesimal generator of an analytic semigroup and has compact resolvent without the assumption of self-adjoint.
