##### 1. On some properties of the hyperspace $\theta (X)$ and the study of the space $\downarrow\theta C(X)$

*Volume 09, Issue 03 , Summer 2020, Pages 185-192*

#####
**Abstract **

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 $\downarrow\theta C(X)$ of the space $\theta (X\times \mathbb I)$.

##### 2. Domination parameters of Cayley graphs of some groups

*Volume 09, Issue 03 , Summer 2020, Pages 193-200*

#####
**Abstract **

In this paper, we investigate domination number, $\gamma$, as well as signed domination number, $\gamma_{_S}$, of all cubic Cayley graphs of cyclic and quaternion groups. In addition, we show that the ...

##### 3. On weakly e*-open and weakly e*-closed Functions

*Volume 09, Issue 03 , Summer 2020, Pages 201-211*

#####
**Abstract **

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 notions of weakly $e^{*}$-open and weakly $e^{*}$-closed functions ...

##### 4. $S$-metric and fixed point theorem

*Volume 09, Issue 03 , Summer 2020, Pages 213-220*

#####
**Abstract **

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 spaces for $\textrm{S}$-metric spaces.

##### 5. Some improvements of numerical radius inequalities via Specht’s ratio

*Volume 09, Issue 03 , Summer 2020, Pages 221-230*

#####
**Abstract **

We obtain some inequalities related to the powers of numerical radius inequalities of Hilbert space operators. Some results that employ the Hermite-Hadamard inequality for vectors in normed linear spaces are also obtained. We improve and generalize some inequalities with respect to ...

##### 6. Algebraic and topological aspects of quasi-prime ideals

*Volume 09, Issue 03 , Summer 2020, Pages 231-236*

#####
**Abstract **

In this paper, we define the new notion of quasi-prime ideal which generalizes at once both prime ideal and primary ideal notions. Then a natural topology on the set of quasi-prime ideals of a ring is introduced which admits the Zariski topology as a subspace topology. The basic properties ...
