Preradical
text:
In mathematics, a preradical is a subfunctor of the identity functor in the category of left modules over a ring with identity. The class of all preradicals over R-mod is denoted by R-pr. There is a natural order in R-pr given by, for any two preradicals σ and τ , σ ≤ τ , if for any left R-module M, σ M ≤ τ M . With this order R-pr becomes a big lattice.
