FILTER BASES AND ω‐PERFECT FUNCTIONS

Abstract

In this paper we introduce some generalizations of somedefinitions which are, closure converge to a point, closure directedtoward a set, almost o-converges to a set, almost condensation point, aset o)H-closed relative, o-continuous functions, weakly o-continuousfunctions, o-compact functions, ro-rigid a set, almost rrl-closedfunctions and ol-perfect functions with several results concerning them.
