Projectivity and duality in a Morita context
Published online by Cambridge University Press: 17 April 2009
Abstract
The concepts of closed submodule, left and right annihilators are generalised and a necessary and sufficient condition on any Morita context is given so that the duality and projectivity between these sets exist. As a special case, we get Hutchinson's necessary and sufficient condition under a weaker hypothesis on the context.
