| Apr 19, 2016 at 18:08 | comment | added | Hans | what you call "the two-sheeted hyperboloid" has as real part a sphere rather than the union of two projective planes. For double covers with branch locus of higher degree I don't see why it should be the union of two projective planes. if it's true, can you give an argument? | |
