Apr 28, 2010 at 5:41 | comment | added | Herb | Thanks, Tim. I know that somehow CP^1 is a basis, but I am trying to understand why. I think it is because CP^1 is the characteristic class for H_2, but I am not sure. Would you please suggest.? | |
Apr 23, 2010 at 2:03 | comment | added | Tim Perutz | Herb, to get you started, can you describe $H_2(\mathbb{CP}^2)$ as an abstract group? Can you write down a basis in terms of embedded oriented surfaces? | |

Apr 22, 2010 at 22:53 | comment | added | David E Speyer | As regards the math, I don't really understand what you are asking, but does is this mathoverflow.net/questions/20336/… the same as your question? | |
