Abstract

In this paper, we study operations on functors in the category of abelian groups simplar to the derivation in the sense of Dold-Puppe. They are defined as derived limits of a functor applied to the relation subgroup over a category of free presentations of the group. The integral homology of the Eilenberg-Maclane space K(Z,3)K(\mathbb Z,3) appears as a part of description of these operations applied to symmetric powers.
