Filter Bases and j-ω-Perfect Mappings
Abstract
This paper consist some new generalizations of some definitions such: j-ω-closureconverge to a point, j-ω-closure directed toward a set, almost j-ω-converges to a set, almostj-ω-cluster point, a set j-ω-H-closed relative, j-ω-closure continuous mappings, j-ω-weaklycontinuous mappings, j-ω-compact mappings, j-ω-rigid a set, almost j-ω-closed mappings andj-ω-perfect mappings. Also, we prove several results concerning it, where j {, δ,, pre, b,}.
