Given a vector space V, its projectivization P(V), sometimes written , is the set of equivalence classes for any in . For example,complex projective space has homogeneous coordinates , with not all .
The projectivization is a manifold with one less dimension than V. In fact, it is covered by the affine coordinate charts,
