Abelian quasigroups and T-quasigroups

, 1994
By means of known results with respect to algebras of a congruence modular variety it is proved that abelian in the sense of McKenzie quasigroups, i.e. quasigroups coinciding with their centre, are T-quasigroups and conversely.

On the use of pairwise balanced designs and closure spaces in the construction of structures of degree at least 3

Le Matematiche, 1990
We prove that a set of v-2 symmetric idempotent latin squares of order v, such that no two of them agree in a off-diagonal position, exists for all odd v>>0.

Parallelograms in quadratical quasigroups

Quasigroups 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.

Double Ward quasigroups.

, 2007
The author proves a one-to-one correspondence between groups and a variety of quasigroups that he calls double Ward quasigroups, denoted by \(\text{DW}(G)\), analogous to the correspondence between groups and Ward quasigroups. In the last part of the paper the author presents two problems. Problem 1.
