| Oct 27, 2010 at 17:49 | comment | added | Oren Ben-Bassat | One can also multiply arbitrary elements of the form $\sum_{i=N}^{\infty} x_{i}t^{i}$ for any integer $N$. I was stopping at a finite number because I was trying to show that for some group structure that already exists the multiplication was induced by maps of topological cells. | |
| Sep 5, 2010 at 20:05 | comment | added | Alison Miller | I'm worried this doesn't actually work: Not every element of the field $\mathbb{C}(t)$ can be written as $\sum_{i=a}^b x_i t^i$, and the set of those that do, do not form a group. I don't see a simple way to fix this. | |
