WebSufficient conditions for an ideal I in R-Mod to be covering are proved. This allows to obtain an alternative proof of the existence of phantom covers of modules. Our approach is inspired by an extension of the standard techniques used in Approximation Theory. Web23. dec 2016. · It is shown that every cotorsion pair for Mod Λ induces a cotorsion pair for Mod Λ. This has some interesting applications, even for the category of finitely presented modules. Another theme of the paper is the interplay between cotorsion and torsion pairs.
