Rings of congruence preserving functions
Let [Formula: see text] denote the near-ring of congruence preserving functions of the group G. We investigate the question “When is [Formula: see text] a ring?”. We obtain information externally via the lattice structure of the normal subgroups of G and internally via structural properties of the g...

| Sumario: | Let [Formula: see text] denote the near-ring of congruence preserving functions of the group G. We investigate the question “When is [Formula: see text] 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. |
