Finite Abelian algebras are fully dualizable
Wolfram Bentz, Pierre Gillibert, Luís Sequeira
We show that every finite Abelian algebra A from congruence-permutable varieties admits a full duality. In the process, we prove that A also allows a strong duality, and that the d…

The modularity conjecture holds for linear idempotent varieties
Wolfram Bentz, Luis Sequeira
The "Modularity Conjecture" is the assertion that the join of two nonmodular varieties is nonmodular. We establish the veracity of this conjecture for the case of linear idempotent…
