Topological pullback, covering spaces, and a triad of Quillen

Jack S. Calcut, John D. McCarthy

We study pullback from a topological viewpoint with emphasis on pullback of covering maps. We generalize a triad of Quillen on properties of the pullback functor.

Topological and algebraic pullback functors

Jack S. Calcut, John D. McCarthy, Jeremy J. Walthers

We give algebraic equivalents for certain desirable properties of pullback functors on categories of coverings and group sets, namely nullity zero, essential injectivity, and essen…
