Filters of strong Sheffer stroke non-associative MV-algebras

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
In this paper, at first we study strong Sheffer stroke NMV-algebra. For getting more results and some classification, the notions of filters and subalgebras are introduced and studied.

Class of Sheffer stroke BCK-algebras

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
In this paper, Sheffer stroke BCK-algebra is defined and its features are investigated. It is indicated that the axioms of a Sheffer stroke BCK-algebra are independent.

On positive commutative tomonoids [PDF]

, 2016
We discuss totally ordered monoids (or tomonoids, for short) that are commutative, positive, and finitely generated. Tomonoids of this kind correspond to certain preorders on free commutative monoids.

Topology on the Spaces Of Orderings of Groups [PDF]

, 2001
A natural topology on the space of left orderings of an arbitrary semi‐group is introduced here. This space is proved to be compact, and for free abelian groups it is shown to be homeomorphic to the Cantor set.

Epimorphisms in varieties of subidempotent residuated structures [PDF]

, 2020
A commutative residuated lattice A is said to be subidempotent if the lower bounds of its neutral element e are idempotent (in which case they naturally constitute a Brouwerian algebra A*).

Singly generated quasivarieties and residuated structures [PDF]

, 2019
A quasivariety K of algebras has the joint embedding property (JEP) iff it is generated by a single algebra A. It is structurally complete iff the free countably generated algebra in K can serve as A.

Algebraic properties of external numbers

Journal of Logic and Analysis, 2011
Neutrices and external numbers were proposed as models of orders of magnitude within nonstandard analysis. We show that the external numbers form a commutative regular semigroup for addition and that the external numbers which are not neutrices form a ...

ON SOME CLASSES OF BCH-ALGEBRAS

, 2001
The concept of a BCH-algebra is a generalization of the concept of a BCI-algebra. It is shown that weakly commutative BCH-algebras are weakly commutative BCI-algebras.

The characterization of Nelson algebras by Sheffer stroke

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this study, Sheffer stroke Nelson algebras (briefly, s-Nelson algebras), (ultra) ideals, quasi-subalgebras, quotient sets, and fuzzy structures on these algebraic structures are introduced.
