In this note, we prove that semilocalization of spaces preserves homotopy monomorphisms and homotopy epimorphisms which induce an isomorphism in fundamental groups, and also prove that homotopy epimorphisms preserve p-nilpotency for every prime or zero p.

In this paper we present comparison theorems in semicubical homotopy theory. Topological versions are more or less well known and have been obtained amongst others by A. DOLD (IS], [7]), I. M. JAMES ([Ill), P. R. HEATH ([9]), S. P. LAM ([15]), and the first author ([Z], [3]). A partially abstract ap
