Abstract: The set of points of upper semicontinuity of multi-valued mappings with a closed graph is studied. A topology on the space of multi-valued mappings with a closed graph is introduced.

Keywords: upper semicontinuity, multifunction, closed graph, $c$-upper semicontinuity, complete uniform space
