WebFormally, a complex projective space is the space of complex lines through the origin of an (n+1)-dimensional complex vector space. The space is denoted variously as P(Cn+1), Pn(C) or CPn. When n= 1, the complex projective space CP1is the Riemann sphere, and when n= 2, CP2is the complex projective plane(see there for a more elementary discussion). spu ship canal project
