The Euler characteristic $${\displaystyle \chi }$$ was classically defined for the surfaces of polyhedra, according to the formula $${\displaystyle \chi =V-E+F}$$ where V, E, and F are respectively the numbers of vertices (corners), edges and faces in the given polyhedron. Any convex polyhedron's surface has … See more In mathematics, and more specifically in algebraic topology and polyhedral combinatorics, the Euler characteristic (or Euler number, or Euler–Poincaré characteristic) is a topological invariant, a number that … See more The polyhedral surfaces discussed above are, in modern language, two-dimensional finite CW-complexes. (When only triangular faces are used, they … See more Surfaces The Euler characteristic can be calculated easily for general surfaces by finding a polygonization of … See more For every combinatorial cell complex, one defines the Euler characteristic as the number of 0-cells, minus the number of 1-cells, plus the number of 2-cells, etc., if this alternating sum is finite. In particular, the Euler characteristic of a finite set is simply its cardinality, and … See more The Euler characteristic behaves well with respect to many basic operations on topological spaces, as follows. Homotopy invariance See more The Euler characteristic of a closed orientable surface can be calculated from its genus g (the number of tori in a connected sum decomposition of the surface; intuitively, the number of "handles") as See more • Euler calculus • Euler class • List of topics named after Leonhard Euler • List of uniform polyhedra See more Webeach face of a particular regular polyhedron, and d to refer to the degree of each vertex. We will show that there are only five di↵erent ways to assign values to n and d that satisfy Euler’s formula for planar graphs. Let us begin by restating Euler’s formula for planar graphs. In particular: v e+f =2. (48)
