Finite generation of congruence preserving functions
@article{Aichinger2015FiniteGO, title={Finite generation of congruence preserving functions}, author={Erhard Aichinger and Marijana Lazic and Nebojsa Mudrinski}, journal={Monatshefte f{\"u}r Mathematik}, year={2015}, volume={181}, pages={35-62} }
We investigate when the clone of congruence preserving functions is finitely generated. We obtain a full description for all finite p-groups, and for all finite algebras with Mal’cev term and simple congruence lattice. The characterization for p-groups allows a generalization to a large class of expansions of groups.

This work investigates the question “When is C_0 (G)$$C0(G) a ring?” and obtains information externally via the lattice structure of the normal subgroups of G and internally via structural properties of the group G.
