Many-valued coalgebraic logic over semi-primal varieties
Alexander Kurz, Wolfgang Poiger, Bruno Teheux
We study many-valued coalgebraic logics with semi-primal algebras of truth-degrees. We provide a systematic way to lift endofunctors defined on the variety of Boolean algebras to e…
New perspectives on semi-primal varieties
Alexander Kurz, Wolfgang Poiger, Bruno Teheux
We study varieties generated by semi-primal lattice-expansions by means of category theory. We provide a new proof of the Keimel-Werner topological duality for such varieties and,…
The Minor Order of Homomorphisms via Natural Dualities
Wolfgang Poiger, Bruno Teheux
We study the minor relation for algebra homomorphims in finitely generated quasivarieties that admit a logarithmic natural duality. We characterize the minor homomorphism posets of…
Classifications of quasitrivial semigroups
Jimmy Devillet, Jean-Luc Marichal, Bruno Teheux
We investigate classifications of quasitrivial semigroups defined by certain equivalence relations. The subclass of quasitrivial semigroups that preserve a given total ordering is…
Associative, idempotent, symmetric, and order-preserving operations on chains
Jimmy Devillet, Bruno Teheux
We characterize the associative, idempotent, symmetric, and order-preserving operations on (finite) chains in terms of properties of (the Hasse diagram of) their associated semilat…
Pivotal decomposition schemes inducing clones of operations
Miguel Couceiro, Bruno Teheux
We study pivotal decomposition schemes and investigate classes of pivotally decomposable operations. We provide sufficient conditions on pivotal operations that guarantee that the…
