SEMI-OPEN AND SEMI-CLOSED SETS IN DITOPOLOGICAL TEXTURE SPACES

In this paper, the counterparts of semi-open and semi-closed sets for ditopological texture spaces are introduced. Some characterizations are presented for semibicontinuous difunctions. Finally, as an application of semi-open and semi-closed sets, the notion of hyperconnected ditopological texture space is defined and some of their characterizations are obtained.
