Upper and Lower Weaky mX - αψ - Continuous Multifunctions

[摘要] In this paper, we introduce the notion of mX - αψ -closed set and investigate some of its properties. We introduceupper/lower mX - αψ -continuous, weakly mX - αψ -continuous, slightly mX - αψ -continuous and almost mX - αψ-continuous multifunctions from a set satisfying certain minimal condition into a topological space and also we obtaintheir characterizations and properties of such multifunctions.
