    This study introduces "homeostatic polygons" formed by angular homeostasis in stable orbits. These polygons require relatively prime vertices and revolutions, with central angles as rational multiples of 2π for finite sides.

    Area of Science:

    • Mathematical Physics
    • Geometric Topology
    • Theoretical Biology

    Background:

    • Regular polygons can exhibit complex behaviors related to orbital dynamics.
    • Angular homeostasis in stable orbits can lead to unique geometric formations.
    • Understanding these formations requires analyzing properties like winding number and sidedness.

    Purpose of the Study:

    • To define and characterize
    • homeostatic polygons
    • arising from angular homeostasis.
    • To establish the mathematical conditions for generating these polygons.
    • To explore potential biological implications of these geometric properties.

    Main Methods:

    • Analysis of regular polygon properties including winding number, sidedness (integer, fractional, irrational), multiplicity, envelopes, and density.

  • Determination of conditions for polygon closure within a single revolution.
  • Application of number theory concepts (relatively prime integers) to polygon generation.
  • Investigation of central angles as rational multiples of 2π.

    • Main Results:

    • A homeostatic polygon is generated if and only if the number of vertices and the number of revolutions are relatively prime.
    • Finite-sided homeostatic polygons necessitate that the central angle between successive vertices is a rational multiple of 2π.
    • The study outlines the mathematical framework for constructing these polygons.

    Conclusions:

    • Homeostatic polygons represent a specific class of regular polygons with unique generation criteria.
    • These geometric principles have potential applications and illustrations in biological systems.
    • The study provides a mathematical foundation for understanding complex polygon formations in stable systems.
