is a note called preservinghomology.pdf that raises (but does not
satisfactorily answer) the question of what it means for an additive
functor between abelian categories to preserve homology. It does work for
functors that are either right or left exact. If anyone has solved (or
even looked seriously at the question) I would appreciate hearing from
them.
