Polynomial interpolation of partial functions in finite algebras with a Mal'cev term
Erhard Aichinger, Mario Kapl, Bernardo Rossi
We provide polynomial completeness results for finite algebras in congruence permutable varieties. In 2001, Idziak and SÅomczy{Å}ska introduced the completeness concept of being…

On polynomial completeness properties of finite Mal'cev algebras
Bernardo Rossi
Polynomial completeness results aim at characterizing those functions that are induced by polynomials. Each polynomial function is congruence preserving, but the opposite need not…
