In the present paper, some additional properties of this notion are studied. Furthermore, we introduce another new notion of topological nearly entropy of f denoted by Ent_n (f) when the whole space X itself is nearly compact. We show the relationship between these two notions for the class of nearly compact subspaces. We also propose new space, namely, R-space in studying the topological nearly entropy on nearly compact and Hausdorff space. As a consequence, the topological nearly entropy of f and it restriction f|K coincides. Finally, some fundamental properties of topological nearly entropy for product space are obtained.", "revisions": [ { "version": "v1", "updated": "2019-08-06T14:21:05.000Z" } ], "analyses": { "subjects": [ "54H20", "37B40" ], "keywords": [ "compact spaces", "topological", "fundamental properties", "additional properties", "product space" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
