Logical entropy of dynamical systems in product MV-algebras and general scheme

open access: yesAdvances in Difference Equations, 2019
The present paper is aimed at studying the entropy of dynamical systems in product MV-algebras. First, by using the concept of logical entropy of a partition in a product MV-algebra introduced and studied by Markechová et al.

On epicomplete $MV$-algebras

open access: yesFLAP, 2016
The aim of the paper is to study epicomplete objects in the category of $MV$-algebras. A relation between injective $MV$-algebras and epicomplete $MV$-algebras is found, an equivalence condition for an $MV$-algebra to be epicomplete is obtained, and it is shown that the class of divisible $MV$-algebras and the class of epicomplete $MV$-algebras are the

Some results on pseudo MV-algebras with n-roots

open access: yesRatio Mathematica
The paper provides a study of pseudo MV-algebras with $n$-roots. We outline their main properties and establish that the class of MV-algebras with $n$-roots forms a variety.

Some Examples of BL-Algebras Using Commutative Rings

open access: yesMathematics, 2022
BL-algebras are algebraic structures corresponding to Hajek’s basic fuzzy logic. The aim of this paper is to analyze the structure of BL-algebras using commutative rings. Due to computational considerations, we are interested in the finite case.

MV-Observables and MV-Algebras

open access: yesJournal of Mathematical Analysis and Applications, 2001
Let \({\mathcal B}(R)\) be the \(\sigma\)-algebra of Borel subsets of \(R\), \({\mathcal T}_{\mathcal B}(R)\) the MV-algebra of all Borel measurable functions \(f: R\to [0,1]\). Usually an observable in an MV-algebra \(M\) is defined as a mapping \(x\) from the Borel \(\sigma\)-algebra \({\mathcal B}(R)\) to \(M\) such that \(x(R)\) is the greatest ...

Identities in the Algebra of Partial Maps [PDF]

open access: yes, 2005
We consider the identities of a variety of semigroup-related algebras modelling the algebra of partial maps. We show that the identities are intimately related to a weak semigroup deductive system and we show that the equational theory is decidable.

MAXIMAL SUBSETS OF PAIRWISE SUMMABLE ELEMENTS IN GENERALIZED EFFECT ALGEBRAS

open access: yesActa Polytechnica, 2013
We show that in any generalized effect algebra (G;⊕, 0) a maximal pairwise summable subset is a sub-generalized effect algebra of (G;⊕, 0), called a summability block.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

open access: yesAdvanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Martingale Convergence Theorem for the Conditional Intuitionistic Fuzzy Probability

open access: yesMathematics, 2020
For the first time, the concept of conditional probability on intuitionistic fuzzy sets was introduced by K. Lendelová. She defined the conditional intuitionistic fuzzy probability using a separating intuitionistic fuzzy probability.
