In this paper, we introduce the dual notion of ss-injective module, namely ss-flat module. The connection between ss-injectivity and ss-flatness is given. Min-Coherent rings, FS-rings, PS-rings, and universally mininjective rings are characterized in terms of ss-flat modules and ss-injectivite modules.
