Some distributivities in GBbi-QRs characterizing Boolean rings

Joanna Kaleta — 2004

Discussiones Mathematicae - General Algebra and Applications

This paper presents some manner of characterization of Boolean rings. These algebraic systems one can also characterize by means of some distributivities satisfied in GBbi-QRs.

The table of characters of some quasigroups

Grzegorz Bińczak; Joanna Kaleta — 2007

Discussiones Mathematicae - General Algebra and Applications

It is known that (ℤₙ,-ₙ) are examples of entropic quasigroups which are not groups. In this paper we describe the table of characters for quasigroups (ℤₙ,-ₙ).

Some finite directly indecomposable non-monogenic entropic quasigroups with quasi-identity

Grzegorz Bińczak; Joanna Kaleta — 2014

Discussiones Mathematicae - General Algebra and Applications

In this paper we show that there exists an infinite family of pairwise non-isomorphic entropic quasigroups with quasi-identity which are directly indecomposable and they are two-generated.

Matrix representation of finite effect algebras

Grzegorz Bińczak; Joanna Kaleta; Andrzej Zembrzuski — 2023

Kybernetika

In this paper we present representation of finite effect algebras by matrices. For each non-trivial finite effect algebra $E$ we construct set of matrices $M (E)$ in such a way that effect algebras $E_{1}$ and $E_{2}$ are isomorphic if and only if $M (E_{1}) = M (E_{2})$ . The paper also contains the full list of matrices representing all nontrivial finite effect algebras of cardinality at most $8$ .
