Nevertheless, lower semi-continuous multifunctions usually possess continuous selections as stated in the [[Michael selection theorem]], which provides another characterisation of [[paracompact]] spaces.<ref>{{cite journal |author=Ernest Michael |author-link=Ernest Michael |date=Mar 1956 |title=Continuous Selections.
