Rings of congruence preserving functions.

ABSTRACT: Let C0(G) denote the near-ring of congruence preserving functions of the group G. We investigate the question "When is C0(G) a ring?". We obtain information externally via the lattice structure of the normal subgroups of G and internally via structural properties of the group G.
