= Euler characteristic of an orbifold
{wiki=Euler_characteristic_of_an_orbifold}
The Euler characteristic of an orbifold is a generalization of the concept of the Euler characteristic of a manifold, adapted to account for the singularities and local symmetries present in orbifolds. An orbifold can be thought of as a space that locally looks like a quotient of a Euclidean space by a finite group of symmetries.
