The algebra of binary trees is affine complete
Andre Arnold, Patrick Cegielski, Serge Grigorieff +1
A function on an algebra is congruence preserving if, for any congruence, it maps pairs of congruent elements onto pairs of congruent elements. We show that on the algebra of binar…

Congruence Preservation, Lattices and Recognizability
Patrick Cegielski, Serge Grigorieff, Irene Guessarian
Looking at some monoids and (semi)rings (natural numbers, integers and p-adic integers), and more generally, residually finite algebras (in a strong sense), we prove the equivalenc…
