Regular Polygonal Partitions of a Tverberg Type [PDF]
A seminal theorem of Tverberg states that any set of $T(r,d)=(r-1)(d+1)+1$ points in $\mathbb{R}^d$ can be partitioned into $r$ subsets whose convex hulls have non-empty $r$-fold intersection. Almost any collection of fewer points in $\mathbb{R}^d$ cannot be so divided, and in these cases we ask if the set can nonetheless be $P(r,d)$--partitioned, i.e.,

Multi-point inerter array and rotation invariance of regular polygon inerter array
Inerter is a pure inertia two-terminal dynamic element. Physical implementations of inerters have made progress in control engineering, mechanical engineering, energy engineering and civil engineering. In this research, an interesting physical phenomenon,

METHODS FOR CONSTRUCTION OF ODD NUMBER POINTED POLYGONS
The purpose of this paper is to present methods for constructing of polygons with an odd number of sides, although some of them may not be built only with compass and straightedge.

Double pyramidal central configurations of Newtonian (N+2)-body problem
For double pyramidal central configurations of the Newtonian (N+2)-body problem where N point particles are positioned at the vertices of a regular N-polygon, and the (N+1)-th and (N+2)-th point-particles are positioned the opposite sides of the plane ...

Summary: Let \(M = M(\Omega)\) be any triangle-free tiling of a planar polygonal region \(\Omega\) with regular polygons. We prove that its face vector \(f(M) = (f_3, f_4, f_5, \ldots)\), its symmetry group \(S(M)\) and the tiling \(M\) itself are uniquely determined by its boundary angles code \(c_a(M) = c_a(\Omega) = (t_1, \ldots, t_r)\), a cyclical ...

A $\textit{regular polygon surface}$ $M$ is a surface graph $(Σ, Γ)$ together with a continuous map $ψ$ from $Σ$ into Euclidean 3-space which maps faces to regular Euclidean polygons. When $Σ$ is homeomorphic to the sphere and the degree of every face of $Γ$ is five, we prove that $M$ can be realized as the boundary of a union of dodecahedra glued ...
