Perfect matchings in hexagonal systems [PDF]

Graphs and Combinatorics, 1985
A hexagonal system (HS) is a finite plane graph with no cut-vertices in which every interior region is a hexagonal unit cell. Assume that the vertices of an HS have been colored white and black. We let B(H) and W(H) denote the sets of black and white vertices, respectively, of the hexagonal system H. An edge-cut (EC) of an HS H is a collection of edges

Double Hexagonal Array Splicing System

2011 Sixth International Conference on Bio-Inspired Computing: Theories and Applications, 2011
In this paper a new system called double splicing on hexagonal arrays is introduced. This system is compared with the other existing systems and the closure properties are studied.

Imaging by a system with a hexagonal pupil

Applied Optics, 2013
We obtain a closed-form analytical expression for the aberration-free point-spread function (PSF) of a system with a hexagonal pupil. The six-fold symmetric PSF consists of a nearly circular bright spot at the center surrounded by a thin dark ring and two each nearly hexagonal bright and dark rings, while maintaining the six-fold symmetry.

A maximal cover of hexagonal systems

Graphs and Combinatorics, 1985
The author proves the following theorem: ''Let H be a peri-condensed HS and K be a cover with maximum cardinality. Then \(H\setminus K\) has a unique 1-factor''. Here is used the following terminology: A hexagonal unit cell is a plane region bounded by a regular hexagon of side length 1. A hexagonal system (HS) is a finite connected plane graph with no
