Relative epimorphisms and monomorphisms in homotopy theory. (English) Zbl 0624.55005

The authors continue their study of (weak) epimorphisms and (weak) monomorphisms in the homotopy category. In particular, they refine earlier results [Proc. Am. Math. Soc. 90, 316-320 (1984; Zbl 0565.55009)], comment on a construction of Y. Félix and J.-M. Lemaire [Topology 24, 41-43 (1985; Zbl 0572.55002)] and investigate the effect of localization on these notions.
