The purpose of the present paper is to investigate weakly closed multifunctions
between topological spaces. We discuss basic properties of weakly closed multifunctions and
some results of Rose and Janković are extended. Our main theorems are concerning some
properties of paracompactness under weakly closed multifunctions. These theorems are
generalizations of some results due to Kovaćević and Singal.
