چکیده
|
In this article, we introduce the concept of co-covering which is the dual of covering concept. then, we prove several theorems being similar to the theorems that have been developed for the covering concept. for example, we provide the lifting criterion for co-coverings of a topological space x, which helps us to classify them by subgroups of the group of all homeomorphisms of x.
