Note on the Chromatic Number of Minkowski Planes: The Regular Polygon Case [PDF]
Studia scientiarum mathematicarum Hungarica (Print), 2023 The famous Hadwiger–Nelson problem asks for the minimum number of colors needed to color the points of the Euclidean plane so that no two points unit distance apart are assigned the same color.

Polygons of quantized vortices in nonlinear photonic waveguides [PDF]
EPJ Web of Conferences, 2023 In a nonlinear optical waveguide with defocusing Kerr-type nonlinearity, we discuss the existence of a type of stationary nonlinear waves with propagation-invariant density profiles, consisting of vortices located at the vertices of a regular polygon ...

Stokes polyhedra for $X$-shaped polyminos [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 Consider a pair of $\textit{interlacing regular convex polygons}$, each with $2(n + 2)$ vertices, which we will be referring to as $\textit{red}$ and $\textit{black}$ ones.

Regular Polygon Central Configuration of the Restricted 1 + N-Body Problem
Universe, 2023 We consider the central configurations of the 1+N-body problem, where N bodies are infinitesimal and the remaining one body is dominant. For regular polygon central configurations, we prove that the masses of all the infinitesimal bodies are equal when N

Entropy of mixing exists only for classical and quantum-like theories among the regular polygon theories [PDF]
Journal of Physics A: Mathematical and Theoretical, 2018 The thermodynamical entropy of a system which consists of different kinds of ideal gases is known to be defined successfully in the case when the differences are described by classical or quantum theory.
