In this paper we deal with varieties of commutative residuated lattices that arise from a specific kind of construction: the twist-product of a lattice. Twist-products were first considered by Kalman in 1958 to deal with ...

O objetivo deste trabalho é apresentar algumas características relacionadas à teoria de reticulados. Restringimos ao estudo dos reticulados obtidos via corpos quadráticos no R². Estudamos, de maneira sucinta, alguns conceitos ...

Concept lattices are used in formal concept analysis for knowledge representation. Formal concept analysis was born in 1982 with the work presented by Wille [1982], who proposed to consider each lattice element as a formal ...

The literature on quantum logic emphasizes that the algebraic structures involved with orthodox quantum mechanics are non distributive. In this paper we develop a particular algebraic structure, the quasi-lattice (J-lattice), ...

The concept of Fock space representation is developed to deal with stochastic spin lattices written in terms of fermion operators. A density operator is introduced in order to follow in parallel the developments of the ...

In this work we study of the theoretical basis that grounding the theory of algebraic lattices and we present some constructions of the E8 lattice with emphasis on the construction presents in the paper A new number field ...

Particle methods have been gaining momentum in the Computational Fluid Dynamics world, for their computational simplicity and inherent parallelism -- This has lead the field to jump to new hardware technologies that exploit ...
