Characterizations of some near-continuous functions and near-open functions

A subset N of a topological space is defined to be a θ-neighborhood of x if there exists an open set U such that x∈U⫅C1   U⫅N. This concept is used to characterize the following types of functions: weakly continuous, θ-continuous, strongly θ-continuous, almost strongly θ-continuous, weakly δ-continu...
