Abstract

In this paper, we first introduce and study the notions of strongly ϕ\phi-flat modules and strongly nonnil-injective modules. And then, we investigate the homology dimensions of modules and rings in terms of these two notions. Finally we give a new homological characterizations of ϕ\phi-Dedekind rings and ϕ\phi-\Prufer\ rings.
