  • On some properties of the hyperspace $theta (X)$ and the study of the space $downarrowtheta C(X)$ 

    Sen, R. (Central Tehran Branch, Islamic Azad University, 2020-09-01)
    The aim of the paper is to first investigate some properties of the hyperspace $theta(X)$, and then in the next article it deals with some detailed study of a special type of subspace $downarrowtheta C(X)$ of the space ...

  • On weakly e*-open and weakly e*-closed Functions 

    Özkoc, M.؛ Erdem, S. (Central Tehran Branch, Islamic Azad University, 2020-09-01)
    The aim of this paper is to introduce and study two new classes of functions called weakly $e^{*}$-open functions and weakly $e^{*}$-closed functions via the concept of $e^{*}$-open set defined by Ekici cite{erd1}. The ...

  • $S$-metric and fixed point theorem 

    Simkhah Asil, M.؛ Sedghi, Sh.؛ Shobe, N.؛ Mitrovic, Z. (Central Tehran Branch, Islamic Azad University, 2020-09-01)
    In this paper, we prove a general fixed point theorem in $textrm{S}$-metric spaces for maps satisfying an implicit relation on complete metric spaces. As applications, we get many analogues of fixed point theorems in metric ...
