摘要

摘要我们考虑了一个自治非线性常微分方程系，在该方程系中，一个不变流形的存在条件在该流形是中心流形的情况下得到满足。众所周知，关于中心不变流形存在性的定理不能用其唯一性来补充说明。我们得到了保证中心不变流形唯一性的充分条件。

On the uniqueness problem for a central invariant manifold

We consider a system of autonomous nonlinear ordinary differential equations for which the existence conditions for an invariant manifold are satisfied in the case where this manifold is central. It is well known that the theorem on the existence of a central invariant manifold cannot be supplemented with the statement of its uniqueness. We obtain sufficient conditions that guarantee the uniqueness of the central invariant manifold.
