Periodic Solutions for Circular Restricted -Body Problems

Abstract and Applied Analysis, 2013
For circular restricted -body problems, we study the motion of a sufficiently small mass point (called the zero mass point) in the plane of equal masses located at the vertices of a regular polygon. By using variational minimizing methods, for some , we

Affine regular polygons

Elemente der Mathematik, 2005
are the sides of a regular (n, k)-gon (see Fig. 1). The regular (n, 1)-gon is an ordinary regular n-gon with directed sides. The regular (n, n − 1)-gon is the same ordinary regular n-gon, only the orientation of the sides are the opposite. For 2 ≤ k ≤ n − 2 a regular (n, k)-gon is a star polygon.

Geometric Singularities of the Stokes Problem

Abstract and Applied Analysis, 2014
When the domain is a polygon of ℝ2, the solution of a partial differential equation is written as a sum of a regular part and a linear combination of singular functions.

A NEW, EFFECTIVE METHOD FOR COMPUTING THE INTERACTION POTENTIAL OF HARD CYCLIC MULTIMER SYSTEMS

TASK Quarterly, 2015
Studies of efficiency of several methods for calculating the interaction potential of a pair of two-dimensional hard cyclic multimers – molecules formed by hard disks (atoms) placed at the vertices of a regular polygon – are reported in this work.

Regular star polygons

Osječki matematički list, 2017
Pravilni zvjezdasti mnogokut je geometrijska figura koja se najčešće susreće u umjetnosti i arhitekturi, ali ima i svoju primjenu pri rješavanju određenih optimizacijskih problema. Takva figura nastaje uzastopnim spajanjem točaka (najčešće nesusjednih) koje su pravilno raspoređene na kružnici pri čemu se postupak spajanja ponavlja sve dok se ne vratimo
