THE EULER NUMBER FROM THE DISTANCE FUNCTION
We present a new method to obtain the Euler number of a domain based on the tangent counts of concentric spheres in ℝ³ (or circles in ℝ², with respect to the center <em>O</em>, that sweeps the domain. This method is derived from the Poincaré-Hopf Theorem, when the index of critical point...
