Remark on Fermat's Last Theorem
Ivan Deriyenko
In this short article we do not prove Fermat's last theorem. We show that the number 2 is an exceptional number in this theorem.
Rectangles in latin squares
I. I. Deriyenko
To get another from a given latin square, we have to change at least 4 entries. We show how to find these entries and how to change them.
Configurations of conjugate permutations
Ivan I. Deriyenko
We describe some configurations of conjugate permutations which may be used as a mathematical model of some genetical processes and crystal growth.
D-loops
Ivan I. Deriyenko, Wieslaw A. Dudek
-loops are loops with the antiautomorphic inverse property. The class of such loops is larger than the class of IP-loops. The smallest -loops which is not an IP-loop has six…
Rigid and super rigid quasigroups
Andriy I. Deriyenko, Ivan I. Deriyenko, Wieslaw A. Dudek
The paper deals with quasigroups having a trivial group of automorphisms and a trivial group of autotopisms. Examples of such quasigroups and methods of their verification are give…
On prolongations of quasigroups
Ivan I. Deriyenko, Wieslaw A. Dudek
We prove that any quasigroup admissing complete or quasicomplete mapping has a prolongation to a quasigroup having one element more.
