Operation approach to ß-open sets and applications

Sažetak

In this paper, we introduce the concept of an operation $\gamma$
on a family of $\beta$-open sets denoted by $\beta O(X)$ in a topological space $(X,\tau)$.
Using the operation $\gamma$ on $\beta O(X)$, we introduce the concept of $\beta$-$\gamma$-open sets, and investigate the related topological properties.
We also introduce the notion of $\beta$-$\gamma$-$T_{i}$ spaces $(i =0, 1/2, 1, 2)$ and study some topological properties on them. Further, we introduce $\beta$-$(\gamma, b)$-continuous maps and investigate basic properties.
Finally, we investigate a general operation approach to $\beta$-closed
graphs of mappings.
