Higher derivations on rings and modules

PE Bland - … Journal of Mathematics and Mathematical Sciences, 2005 - Wiley Online Library
Let τ be a hereditary torsion theory on ModR and suppose that Qτ: ModR→ ModR is the
localization functor. It is shown that for all R‐modules M, every higher derivation defined on …

PE Bland - Journal of Pure and Applied Algebra, 2006 - Elsevier
Differential torsion theories are introduced and it is shown that for a hereditary torsion theory
τ every derivation on an R-module M has a unique extension to its module of quotients if and …

If $\tau $ is a hereditary torsion theory on $\bold {Mod} _ {R} $ and $ Q_ {\tau}:\bold {Mod} _
{R}\rightarrow\bold {Mod} _ {R} $ is the localization functor, then we show that every $ f …
