摘要:In this paper we consider the semigroups of quasi-open transformations. A map f between topological spaces X and Y is quasi-open if for any non-empty open set U ⊂ X, the interior of f (U) in Y is non-empty. We give abstract characterizations of semigroups of continuous quasi...

摘要:In this paper we consider the semigroups of quasi-open functions. A function f between topological spaces X and Y is quasi-open if for any non-empty open set U⊂X, the interior of f(U) in Y is non-empty. We give abstract characterization of semigroups of quasi-open functions ...
