The coefficients of transitivity of the posets of MM-type being the highest supercritical poset

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2022
The representations of partially ordered sets (abbreviated as posets), introduced by L. A. Nazarova and A. V. Roiter (in matrix form) in 1972, play an important role in the modern representation theory. In his first paper on this topic M. M.

The Estimating of the Number of Lattice Tilings of a Plane by a Given Area Centrosymmetrical Polyomino

open access: yesМоделирование и анализ информационных систем, 2015
We study a problem about the number of lattice plane tilings by the given area centrosymmetrical polyominoes. A polyomino is a connected plane geomatric figure formed by joiining a finite number of unit squares edge to edge.
