Abstract : We investigate the relation between the notion of $e$-exactness, recently introduced by Akray and Zebary, and some functors naturally related to it, such as the functor $P\colon{}$Mod-$R\to{}$Spec$($Mod-$ R)$, where Spec$($Mod-$ R)$ denotes the spectral category of Mod-$R$, and the localization functor with respect to the singular torsion theory.
Keywords : Relative exactness of sequences
