In this paper, the notions of fuzzy F∗‐simply connected spaces and fuzzy F∗‐structure
homeomorphisms are introduced, and further fuzzy F∗‐structure homeomorphism between …

This study introduces the concepts of a fuzzy ℑ*-structure locally compact space and fuzzy
ℑ*-structure evaluation maps are introduced and a fuzzy ℑ*-structure covering the map …

In this paper, the concept of fuzzy¿∗-structure isomorphisms between¿∗-fundamental
groups are studied. Also it is shown that, for every fuzzy¿∗-structure continuous function …

In this disquisition, the notion structures is introduced. The intend of this article is to study the
notions of homotopy, path homotopy and fundamental group via structure which is a triplet …

In this paper, the notions of fuzzy F∗-simply connected spaces and fuzzy F∗-structure
homeomorphisms are introduced, and further fuzzy F∗-structure homeomorphism between …

In this paper we study and define the concept of the fundamental group of rough topological
spaces (RTSs), which deeply depends on the concepts of rough sets (RSs) and rough …
