【摘要】 拓扑空间的仿紧性质是拓扑空间的重要性质 ,为了讨论拓扑空间的仿紧性质以及仿紧性质的各种推广 ,讨论了拓扑空间的强收缩性质 ,得了如下结果 :拓扑空间是强收缩的充要条件是它是正规的且对它的任一单增开覆盖存在 σ-闭加细 .这一结果是有关这一方面的一些结果的深化和方法的统一更多还原

【Abstract】 The paracompactness of a topology space is important,in order to discuss the paracompactness of a topology space and the generalizations of it,the shringking property of a topology space is discussed.The following result is got.A space is shrinking if and only if it is normal and there is a σ closed rifinement for its any increasing open cover.The result is to deepen the results of this aspect and unify the methods of this aspect.更多还原
