Euler–Poincare characteristic( nonconvex polyhedra )


n mathematics, and more specifically in algebraic topology and polyhedral combinatorics, the Euler characteristic (or Euler–Poincaré characteristic) is a topological invariant, a number that describes a topological space’s shape or structure regardless of the way it is bent.Any convex polyhedron’s surface has Euler characteristic equal to 2.
