Separating sets by lower and upper semicontinuous functions with a closed graph

open access: yesQuaestiones Mathematicae, 2016
In this paper we characterize the pairs (A- ;A+) of disjoint subsets of perfectly normal topological space which can be separated by a lower and an upper semicontinuous function with a closed graph.Mathematics Subject Classification (2010): 54C30, 26A15,
