Pierce stalks in preprimal varieties
D. Vaggione, W. J. Zuluaga Botero
An algebra is called \textit{preprimal} if is finite and $\func{Clo}(\mathbf{P})$ is a maximal clone. A \textit{preprimal variety} is a variety generated…
Semantical conditions for the definability of functions and relations
Miguel Campercholi, Diego Vaggione
Let be first order languages, let be a relation symbol, and let be a class of…
On structural completeness vs almost structural completeness problem: A discriminator varieties case study
Miguel Campercholi, Michal M. Stronkowski, Diego Vaggione
We study the following problem: Determine which almost structurally complete quasivarieties are structurally complete. We propose a general solution to this problem and then a solu…
Varieties with Definable Factor Congruences
Pedro Sánchez Terraf, Diego J. Vaggione
We study direct product representations of algebras in varieties. We collect several conditions expressing that these representations are "definable" in a first-order-logic sense,…
