Please keep on answering. | |

[I am pretty good at algebraic geometry...for a number theorist.] Perhaps I should exercise more restraint. | |
| Apr 22, 2010 at 4:31 | comment | added | Pete L. Clark | I mean the map which appears in the universal coefficient theorem for cohomology...which is indeed defined by functoriality. | |
| Apr 22, 2010 at 4:28 | comment | added | Mariano Suárez-Álvarez | What do you mean by "(universal coefficient)"? Isn't the map you want just the one given by functoriality? | |
| Apr 22, 2010 at 3:53 | comment | added | Kevin H. Lin | Yeah, ok, nevermind. | |
| Apr 22, 2010 at 3:33 | comment | added | Pete L. Clark | Agreed. But for a line bundle, what else would it be? | |
| Apr 22, 2010 at 3:17 | comment | added | Kevin H. Lin | This is the first Chern class, usually denoted $c_1$. | |
