State maps on semihoops

open access: yesOpen Mathematics, 2018
In this paper, we introduce the notion of state maps from a semihoop H1 to another semihoop H2, which is a generalization of internal states (or state operators) on a semihoop H.

Spectra and reticulation of semihoops

open access: yesOpen Mathematics, 2022
In this article, we further study the filter theory of semihoops. Moreover, we use the prime (maximal) filters to construct the prime (maximal) spectrum on semihoops, and prove that the prime spectrum is a compact T0{T}_{0} topological space and that the

Perfect and bipartite IMTL-algebras and disconnected rotations of prelinear semihoops [PDF]

open access: yesArchive for Mathematical Logic, 2005
IMTL logic was introduced in [12] as a generalization of the infinitely-valued logic of Lukasiewicz, and in [11] it was proved to be the logic of left-continuous t-norms with an involutive negation and their residua.

Module structures and filters on semihoops [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, we study modules and filters on semihoops. Firstly, we introduce the definition of modules on semihoops and give some examples to illustrate it. Also, we get some significant results related to modules on semihoops. If the semihoop $G$ can

Equivalences between subcategories of MTL-algebras via Boolean algebras and prelinear semihoops

open access: yesJournal of Logic and Computation, 2017
This article studies the class of strongly perfect MTL-algebras, i.e. MTL-algebras having an involutive co-radical, and the variety they generate, namely SBP0. Once these structures will be introduced, we will first establish categorical equivalences for

Split exact sequences of finite MTL-chains [PDF]

open access: yes, 2021
This paper is devoted to presenting ordinal sums of MTL-chains as a particular case of split short exact sequences of finite chains in the category of semihoops.

On finite MTL-algebras that are representable as poset products of archimedean chains [PDF]

open access: yes, 2020
We obtain a duality between the category of locally unital finite MTL-algebras and the category of finite labeled trees. In addition we prove that certain poset products of MTL-algebras are in fact, sheaves of MTL-chains over Alexandrov spaces.

Hyperstates of Involutive MTL-Algebras that Satisfy (2x)^2=2(x^2)

open access: yes, 2021
States of MV-algebras have been the object of intensive study and attempts of generalizations. The aim of this contribution is to provide a preliminary investigation for states of prelinear semihoops and hyperstates of algebras in the variety generated ...

Algebraization in quasi-Nelson logics [PDF]

open access: yes, 2023
Quasi-Nelson logic is a recently introduced generalization of Nelson’s constructive logic with strong negation to a non-involutive setting. The present work proposes to study the logic of some fragments of quasi-Nelson logic, namely: pocrims (ℒQNP) and

Generalized continuous and left-continuous t-norms arising from algebraic semantics for fuzzy logics [PDF]

open access: yes, 2010
This paper focuses on the issue of how generalizations of continuous and left-continuous t-norms over linearly ordered sets should be from a logical point of view.
