摘要

在无限维环面上，考虑了一类特殊的微分同态，其中无限维实巴拿赫空间为抽象整数格。它由可逆有界线性算子和-光滑周期加法的映射组成。得到了保证这种映射是双曲的(即是ananosov微分同态)的充分必要条件。参考书目:15篇。

A hyperbolicity criterion for a class of diffeomorphisms of an infinite-dimensional torus

On an infinite-dimensional torus , where is an infinite-dimensional real Banach space and is an abstract integer lattice, a special class of diffeomorphisms is considered. It consists of the maps equal to sums of invertible bounded linear operators preserving and -smooth periodic additives. Necessary and sufficient conditions ensuring that such maps are hyperbolic (that is, are Anosov diffeomorphisms) are obtained. Bibliography: 15 titles.
