Abstract

We generalize the well-known fact that for a pair of Morita equivalent ringsR andS their maximal rings of quotients are again Morita equivalent: If τ n (M) denotes the torsion theory cogenerated by the direct sum of the firstn+1 injective modules forming part of the minimal injective resolution ofM then ατ n (R)=τ n (S) where α is the category equivalenceR-Mod→S-Mod. Consequently the localized ringsR τn (R) andS τ n (S) are Morita equivalent.
