By John Clark, Christian Lomp, N. Vanaja, Robert Wisbauer

Extending modules are generalizations of injective modules and, dually, lifting modules generalize projective supplemented modules. This duality shows a undeniable asymmetry. whereas the idea of extending modules is easily documented in monographs and textual content books, the aim of this monograph is to supply a radical research of vitamins and projectivity stipulations had to examine sessions of modules on the topic of lifting modules.
