%0 Journal Article %T Contra-semicontinuous Functions %A Julian Dontchev %A Takashi Noiri %J Mathematics %D 1998 %I arXiv %X The aim of this paper is to introduce and study the concept of a contra-semicontinuous function and further investigate the class of strongly $S$-closed spaces. We obtain some new decompositions of generalized continuous functions. %U http://arxiv.org/abs/math/9810079v1
