Parastrophic-orthogonal ternary medial quasigroups with 3 and 4 distinct parastrophes

open access: yesМатематика, інформатика, фізика: наука та освіта
In the article, we study parastrophic-orthogonal ternary quasigroups: namely, group isotopes which have 3 and 4 distinct parastrophes. The necessary and sufficient conditions for ternary medial quasigroups with 3 and 4 distinct parastrophes to be ...

Parallelograms in quadratical quasigroups

open access: yesQuasigroups and related systems, 2010
The "geometric" concept of parallelogram is introduced and investigated in a general quadratical quasigroup and geometrical interpretation in a quadratical quasigroup $C(1/2(1+i)))$ is given. Some statements about relationships between the parallelograms and some other geometric structures in a general quadratical quasigroup will be also considered.

Periodic quasigroup string transformations [PDF]

open access: yes, 2009
Given a finite quasigroup (Q,*), a quasigroup string transformations e_l and d_l over the strings of elements from Q are defined as follows. e_l(a_1a_2 ... a_n) = b_1b_2 ... b_n if and only if b_i = b_{i-1}*a_i and d_l(a_1a_2 ... a_n)= b_1b_2 ...

On the construction of cyclic quasigroups

open access: yesDiscrete Mathematics, 1973
AbstractLet F(x,y) be the free groupoid on two generators x and y. Define an infinite class of words in F(x,y) by w0(x,y) = x,w1(x,y) = y and wi+2(x,y) = wi(x,y)wi+1(x,y). An identity of the form w3n(x,y) = x is called a cyclic identity and a quasigroup satisfying a cyclic identity is called a cyclic quasigroup.

Linear quasigroups. I

open access: yes, 2011
The article is devoted to linear quasigroups and some of their generalizations. In the first part main definitions and notions of the theory of quasigroups are given. In the second part some elementary properties of linear quasigroups and their generalizations are presented.
