Quasi-Exact Coulomb Dynamics of n Charges n-1 of Which Are Equal

Advances in Mathematical Physics, 2017
For n≥3 point charges n-1 of which are negative and equal quasi-exact periodic solutions of their Coulomb equation of motion are found. These solutions describe a motion of the negative charges around a coordinate axis in such a way that their ...

Regular Polygon Surfaces

, 2018
A $\textit{regular polygon surface}$ $M$ is a surface graph $( , )$ together with a continuous map $ $ from $ $ into Euclidean 3-space which maps faces to regular Euclidean polygons. When $ $ is homeomorphic to the sphere and the degree of every face of $ $ is five, we prove that $M$ can be realized as the boundary of a union of dodecahedra ...

When is a polygon circumscribing a regular polygon again regular?

, 1993
Let \({\mathcal A}\) be a regular \(n\)-gon with vertices \(A_ 1,A_ 2,\ldots,A_ n\) and edge-length =1, which is inscribed in \({\mathcal P}\), an \(n\)-gon with vertices \(P_ 1,P_ 2,\ldots,P_ n\), in such a way that \(A_ 1P_ 1=A_ 2P_ 2=\cdots=A_ nP_ n\). The main results of this paper are given in the following theorem. Theorem 1. If \(n=3\) or 4 or \(

Analysis and Insights on Regular Polygon Loop Antennas With Attenuating Current: Axial Ratio Deterioration and Recovery

IEEE Access
The current along a loop antenna is characterized by either a propagation constant ( $\alpha + j\beta $ ) or ( $\alpha - j\beta $ ). Understanding the impact of the propagation constant on the axial ratio is crucial for maintaining the performance of ...

Regular polygons

The construction of regular polygons with a compass and straightedge is a well-known task and this problem has interested mathematicians for a long time. In particular, for a long time they could not answer the question of whether is it possible to construct a regular 17-gon with a compass and straightedge. C. F. Gauss solved this problem in 1796.

Periodic skyrmionic textures via conformal cartographic projections

APL Photonics
We find periodic skyrmionic textures via conformal cartographic projections that map either an entire spherical parameter space or a hemisphere onto every regular polygon that provides regular tessellations of the plane.

Spatial hotspot detection using polygon propagation

International Journal of Digital Earth, 2019
Spatial scan statistics is one of the most important models in order to detect high activity or hotspots in real world applications such as epidemiology, public health, astronomy and criminology applications on geographic data. Traditional scan statistic
