| Jun 17, 2013 at 22:21 | comment | added | meh | This fails systematically, in $P^n}$, the only cohomology invariant is "degree". All sorts of non-homeomorphic varities can be embedded as projective varieties of the same degree. n= 2 d= 3 allows for elliptic curves and rational normal curve of degree 3. This can be gussied up for anything except degree 1 and (sometimes ?) 2. | |
