Web2. The complex projective line CP1 For purposes of complex analysis, a better description of a one-point compacti cation of C is an instance of the complex projective space CPn, a compact space containing Cn, described as follows. Let ˘be the equivalence relation on Cn+1 f 0gby x˘ywhen x= yfor some 2C . Thus, x˘y means that xand ylie on the ... WebMark Hunacek. , on. 09/18/2014. ] Projective geometry, like Euclidean geometry, can be developed both from a synthetic (axiomatic) and analytic point of view. In the two-dimensional case of projective planes, for example, three simple and pleasingly symmetric axioms suffice: one that guarantees the existence of four distinct points, no three of ...
