Symmetry Breaking: One-Point Theorem
Symmetry breaking is crucial in many areas of physics, mathematics, biology, and engineering. We investigate the symmetry of regular convex polygons, non-convex regular polygons (stars), and symmetric Jordan curves/domains. We demonstrate that removing a

1. FIRST AND LAST POINT OF A CURVE
, 2008 Summary. The proof of the Jordan Curve Theorem according to [11] is continued. The notions of the first and last point of a oriented arc are introduced as well as ordering of points on a curve in E 2 ...

El teorema de Jordan y los grados planares
, 2016 En este trabajo estudiamos el teorema de la curva de Jordan, con énfasis especial en algunos aspectos relacionados con la Teoría de Grafos, más exactamente con la planaridad.

Jordan curves in the digital plane
, 2014 We discuss certain interrelated pretopologies on the digital plane Z2 including the Khalimsky topology and several other topologies on Z2. We present a digital analogue of the Jordan curve theorem for each of the pretopologies to demonstrate that they ...

Groupoids, the Phragmen-Brouwer Property and the Jordan Curve Theorem
, 2006 We publicise a proof of the Jordan Curve Theorem which relates it to the Phragmen-Brouwer Property, and whose proof uses the van Kampen theorem for the fundamental groupoid on a set of base points.
