This applies to the I-indexed diagrams in the category of R-modules, with R a commutative ring ; it is not necessarily true in an arbitrary abelian category ( see Roos ' " Derived functors of inverse limits revisited " for examples of abelian categories in which lim ^ n, on diagrams indexed by a countable set, is nonzero for n > 1 ).

The morphisms in E between R → S < sub > 1 </ sub > and R → S < sub > 2 </ sub > are commutative triangles of the form ( R → S < sub > 1 </ sub >, R → S < sub > 2 </ sub >, S < sub > 1 </ sub > → S < sub > 2 </ sub >) where S < sub > 1 </ sub > → S < sub > 2 </ sub > is a ring map ( which preserves the identity ).
