We introduce a property weaker than congruence-permutability and show that every d0-algebra has this property. We also show that in general d0-algebras are not congruence-permutable, and that a sufficient condition for a d0-algebra to be congruence-permutable is being directed.

Abstract
We introduce a property weaker than congruence-permutability and show that every d0-algebra has this property. We also show that in general d0-algebras are not congruence-permutable, and that a sufficient condition for a d0-algebra to be congruence-permutable is being directed.File in questo prodotto:
