Abstract

We introduce and study the notion of a locally proper map between topological spaces.We show that fundamental constructions of sheaf theory, more precisely proper base change, projection formula, and Verdier duality, can be extended from continuous maps between locally compact Hausdor spaces to separated locally proper maps between arbitrary topological spaces.
