摘要

我们为双面线性延迟-差分方程及其演化图建立了双曲性和另外两个性质的等价性。这两个性质是相对于不同空间对的可接受性和方程的乌兰-希尔斯稳定性（同样相对于不同空间）。这给出了线性动力系统的重要特性，即由相关演化图决定的自主动力系统的相应特性。

Two-sided delay-difference equations and evolution maps

We establish the equivalence of hyperbolicity and of two other properties for a two-sided linear delay-difference equation and its evolution map. These two properties are the admissibility with respect to various pairs of spaces, and the Ulam–Hyers stability of the equation, again with respect to various spaces. This gives characterizations of important properties of a linear dynamical system in terms of corresponding properties of the autonomous dynamical system determined by the associated evolution map.
