Geometric constructibility of polygons lying on a circular arc
Delbrin Ahmed, Gábor Czédli, Eszter K. Horváth
For a positive integer , an -sided polygon lying on a circular arc or, shortly, an -fan is a sequence of points on a circle going counterclockwise such that the "tot…
A general framework for island systems
Stephan Foldes, Eszter K. Horváth, Sándor Radeleczki +1
The notion of an island defined on a rectangular board is an elementary combinatorial concept that occurred first in [G. Czédli, The number of rectangular islands by means of distr…
Invariance groups of finite functions and orbit equivalence of permutation groups
Eszter K. Horváth, Géza Makay, Reinhard Pöschel +1
Which subgroups of the symmetric group S_n arise as invariance groups of n-variable functions defined on a k-element domain? It appears that the higher the difference n-k, the more…
Elementary proof techniques for the maximum number of islands
János Barát, Péter Hajnal, Eszter K. Horváth
Islands are combinatorial objects that can be intuitively defined on a board consisting of a finite number of cells. Based on the neighbor relation of the cells, it is a fundamenta…
