The variety generated by order algebras [PDF]

open access: yesAlgebra Universalis, 2002
Every ordered set can be considered as an algebra in a natural way. We investigate the variety generated by order algebras. We prove, among other things, that this variety is not finitely based and, although locally finite, it is not contained in any ...

Varieties of BL-algebras

Soft Computing, 2005
This paper is an overview on the lattice Sub(BL) of the subvarieties of the variety BL of the BL-algebras. The authors describe the most important sublattices of Sub(BL). In Section 3 they deal with the lattice of subvarieties of the join of the varieties of Wajsberg algebras, Gödel algebras and Product algebras.
