On decomposition of continuity, B-quasicontinuity and closed graph

摘要

In this article, we establish a new decomposition of continuity, that is associated with the property of the closed graph. This decomposition of continuity generalizes the results of P. Long and E. McGehee [1], J. Dobos [5] and J. Borsik [6]. There are also some interesting facts related to bilateral quasicontinuity revealed in this work. (C) 2019 Elsevier B.V. All rights reserved.
