$\beta$-Open and $\beta$-Closed Sets in Ditopological Texture Spaces
Ş. Dost, L. M. Brown, R. Ertürk
We define $\beta$-open and $\beta$-closed sets in a ditopological texture space and go on to study $\beta$-compactness and $\beta$-cocompactness, $\beta$-stability and $\beta$-costability, and $\beta$-dicompactness.
