摘要
利用范畴论中范畴与函子的概念,定义了动力系统范畴T到包络半群范畴E的共变函子F1及范畴T到范畴E*的反变函子F2,并分别讨论了范畴T中乘积系统的包络半群与范畴E中包络半群直积的一致性及范畴T中逆极限系统的包络半群与范畴E中包络半群逆极限的一致性.
AbIn this paper, we define a covariant functor F1 from the category of dynamical system T to the category of enveloping semigroup E and a contravariant functor F2 from the category T to the category E* by means of the concepts of category and functor in categorical theory. In addition, the questions are discussed whether the enveloping semigroup of product space in the category T is equal to the product of the enveloping semigroups in the category E and the enveloping semigroup of inverse limit space in the category T is equal to the inverse limit of the enveloping semigroups in the category E.
