ISSN 1024-7696.1024-7696https://msuir.usm.md/handle/123456789/4947We extend the concept of the ergodic set [1] – [2] from topological trans-formation groups to topological transformation semigroups. We investigate, in par-ticular, connections between ergodicity, weak ergodicity, topological transitivity andminimality of the Whitney’s sum of extensions of topological transformation semi-groupsenergodicdistaltransformation semigroupArticle
