A Note on 3×3-valued Łukasiewicz Algebras with Negation

Bulletin of the Section of Logic, 2021
In 2004, C. Sanza, with the purpose of legitimizing the study of n × m-valued Łukasiewicz algebras with negation (or NSn×m-algebras) introduced 3 × 3-valued Łukasiewicz algebras with negation.

Varieties of unary-determined distributive $\ell$-magmas and bunched implication algebras [PDF]

Logical Methods in Computer Science
A distributive lattice-ordered magma ($d\ell$-magma) $(A,\wedge,\vee,\cdot)$ is a distributive lattice with a binary operation $\cdot$ that preserves joins in both arguments, and when $\cdot$ is associative then $(A,\vee,\cdot)$ is an idempotent semiring.

Application of the BLUPe predictor in the selection of potential soybean varieties for Orinoquia

Agronomía Colombiana, 2022
The Colombian Orinoquía and the Altillanura subregion show comparative and competitive advantages for soybean production (edaphoclimatic conditions, cost-benefit ratio, potential area, and location), essential food with a high protein content (~37%) and

The lattice of 𝑙-group varieties [PDF]

, 1980
For any type of abstract algebra, a variety is an equationally defined class of such algebras. Recently, attempts have been made to study varieties of lattice-ordered groups (l-groups).

The Order of Hypersubstitutions of Type (2,1)

International Journal of Mathematics and Mathematical Sciences, 2011
Hypersubstitutions are mappings which map operation symbols to terms of the corresponding arities. They were introduced as a way of making precise the concept of a hyperidentity and generalizations to 𝑀-hyperidentities.

The Amalgamation Property for Varieties of Lattices [PDF]

Transactions of the American Mathematical Society, 1984
There are precisely three varieties of lattices that satisfy the amalgamation property: trivial lattices, distributive lattices, and all lattices.

On the Equational Theory of Lattice-Based Algebras for Layered Graphs

Axioms
Layered algebras are introduced and used to express layered graphs. Layered graphs are considered to be a highly effective abstract tool to manage the difficulty in conceptualizing and reasoning regarding complex systems related to coding in email ...
