Two-valued states on Baer $^*$-semigroups [PDF]

open access: yes, 2014
In this paper we develop an algebraic framework that allows us to extend families of two-valued states on orthomodular lattices to Baer $^*$-semigroups. We apply this general approach to study the full class of two-valued states and the subclass of Jauch-

New topology in residuated lattices

open access: yesOpen Mathematics, 2018
In this paper, by using the notion of upsets in residuated lattices and defining the operator Da(X), for an upset X of a residuated lattice L we construct a new topology denoted by τa and (L, τa) becomes a topological space.

Remarks on an algebraic semantics for paraconsistent Nelson's logic

open access: yesManuscrito, 2011
In the paper Busaniche and Cignoli (2009) we presented a quasivariety of commutative residuated lattices, called NPc-lattices, that serves as an algebraic semantics for paraconsistent Nelson's logic.

Residuated skew lattices with modal operator

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
In this paper, we define modal operators in residuated skew lattices and prove some fundamental properties of monotone modal operators on residuated skew lattices (RSL). We prove that the composition of two modal operators is a modal operator if and only

Left and right compatibility of strict orders with fuzzy tolerance and fuzzy equivalence relations [PDF]

open access: yes, 2015
The notion of extensionality of a fuzzy relation w.r.t. a fuzzy equivalence was first introduced by Hohle and Blanchard. Belohlavek introduced a similar definition of compatibility of a fuzzy relation w.r.t. a fuzzy equality.

Untyping Typed Algebras and Colouring Cyclic Linear Logic [PDF]

open access: yesLogical Methods in Computer Science, 2012
We prove "untyping" theorems: in some typed theories (semirings, Kleene algebras, residuated lattices, involutive residuated lattices), typed equations can be derived from the underlying untyped equations.

n-Fold Fantastic and n-Fold Involutive Ideals in Bounded Commutative Residuated Lattices

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2022
In this paper, we introduce the concepts of n-fold obstinate ideals, n-fold normal ideals, n-fold fantastic ideals and n-fold involutive ideals in residuated lattices, state and prove some of their properties.

Fuzzy inequational logic [PDF]

open access: yes, 2015
We present a logic for reasoning about graded inequalities which generalizes the ordinary inequational logic used in universal algebra. The logic deals with atomic predicate formulas of the form of inequalities between terms and formalizes their semantic
