This study models angular homeostasis, revealing stable, self-intersecting curves that resemble biological patterns. These findings offer insights into morphogenesis and developmental biology.

Area of Science:

  • Mathematical Biology
  • Developmental Biology
  • Morphogenesis

Background:

  • Angular homeostasis models describe how systems maintain a preferred angle.
  • Previous models did not fully account for correction functions with single maxima.

Purpose of the Study:

  • To extend angular homeostasis models to include specific correction functions.
  • To analyze the resulting curve structures, their stability, and symmetries.

Main Methods:

  • Mathematical modeling of angular homeostasis.
  • Analysis of differential equations governing curve formation.
  • Investigation of curve properties like periodicity and symmetry.

Main Results:

  • Identified stable and asymptotically stable solutions consisting of self-intersecting curves.

  • Characterized conditions for curve periodicity and described their symmetries.
  • Observed patterns with loops, reflectional symmetry, and cyclic rotation groups.

    • Conclusions:

    • The extended model generates complex, biologically relevant patterns.
    • These patterns show resemblance to lobulated biological structures.
    • Findings have implications for understanding morphogenesis and developmental processes.
