##### 1. Continuity of some mappings on a group via semi-regular topology

M. Ram; S. K. Elagan

Volume 10, Issue 03 , Summer 2021, Pages 179-185

##### Abstract
‎For a given topological space $(X‎, ‎~\Im)$,‎ ‎there is a coarser topology on $X$ which is called the semi-regular topology on $X$ (generated by regularly open subsets) and it is denoted by $\Im^{\delta}$‎. ‎In this paper‎, ‎we study the continuity of the group operation ...  Read More

##### 2. An algebraic perspective on neutrosophic sets: fields and linear spaces

V. Cetkin; B. Pazar Varol; H. Aygun

Volume 10, Issue 03 , Summer 2021, Pages 187-198

##### Abstract
In this work, we intend to introduce and study another algebraic structure of single-valued neutrosophic sets called neutrosophic field as a continuation of our investigations on neutrosophic algebraic structures. For this goal, we define the concept of neutrosophic fields and observe some of their basic ...  Read More

##### 3. A closure operator versus purity

M. Ghorbani

Volume 10, Issue 03 , Summer 2021, Pages 199-203

##### Abstract
‎Any notion of purity is normally defined in terms of‎ ‎solvability of some set of equations‎. ‎To study mathematical notions‎, ‎such as injectivity‎, ‎tensor products‎, ‎flatness‎, ‎one needs to have some categorical and‎ ‎algebraic ...  Read More
