Orientifold

In Theory of the cords, a orientifold is a construction generalizing the concept of Orbifold and which consists in combining a transformation of parity of the Feuille of universe of the cord (which exchanges sectors holomorphic and anti-holomorphic on this one) with a transformation of parity of the Espace-temps.
