On spaces with star kernel Menger

چکیده

Given a topological property $$\mathcal{P}$$ , space $$X$$ is called star- if for any open cover $$\mathcal{U}$$ of the there exists set $$Y\subseteq X$$ with such that $$St(Y,\mathcal{U})=X$$ ; $$Y$$ star kernel . In this paper, we introduce and study spaces Menger, is, determined by Menger spaces, denoted $$S_{\rm fin}(\mathcal{O},\mathcal{O})$$ Some examples are given to show relationship some other related properties studied previously, behaviour respect subspaces, products, continuous images preimages investigated. Additionally, comments on selection principles theory given. Particularly, questions posed Song within addressed. Finally, several new introduced as well general them posed.

Some Remarks on Almost Menger Spaces and Weakly Menger Spaces

{V : V ∈ Vn} = X . Clearly, every Menger space is almost Menger and every almost Menger space is weakly Menger, but the converses do not hold (see Examples 2.1 and 2.2). On the study of weakly Menger spaces, almost Menger spaces and Menger spaces, the readers can see the references [2, 3, 4, 5, 6]. Here we investigate the relationships among almost Menger spaces, weakly Menger spaces and Menger...

Weak Compatibility in Menger Spaces

In this paper, we prove a common fixed point theorem for weakly compatible maps in Menger space which generalizes the result of Kutukcu [6] without appeal to continuity on this space. We also cited an example in support of our result. Mathematics Subject Classification: Primary 47H10, Secondary 54H25

On Common Fixed Point For Compatible mappings in Menger Spaces

In this paper the concept of compatible map in menger space has been applied to prove common fixed point theorem. A fixed point theorem for self maps has been established using the concept of compatibility of pair of self maps.

Common Fixed Point Theorems in Menger Spaces

In this paper Theorem 3.1 of Kubiaczyk and Sushil Sharma [5] is shown to hold even under weaker hypothesis (Theorem 2.2) and we obtain a fixed point theorem (Theorem 2.3) involving occasionally weakly compatible maps and also prove a coincidence point theorem (Theorem 2.4) for a pair of self maps under certain conditions. Examples are provided to show that the hypothesis in Theorems 2.3 and 2.4...

Common fixed point theorems in Menger spaces

Probabilistic metric space was first introduced by Menger [6]. Later, there are many authors who have some detailed discussions and applications of a probabilistic metric space, for example, we may see Schweizer and Sklar [8]. Besides, there are many results about fixed point theorems in a probabilistic metric space with contractive types having appeared; we may see the papers [1–3, 9–12]. In t...
