| Sep 19, 2015 at 7:06 | comment | added | S. Carnahan♦ | With the topology introduced in the edit, it suffices to show that for any translate of $I_{n,m}$ there is a polynomial in $1+T$ that lies in that open set. Further explanation can be sought at Math.SE. | |

Describe the relevant topology on $\mathbb{Z}_p[[T]]$ and made explicit what is meant by a topological generator.

| Sep 18, 2015 at 19:15 | comment | added | Sameer Kulkarni | This is not a hoework. I was reading about standard Iwasawa algebras and the authors made a claim that trying to understand which I asked this question. And this is my first question on Overflow. I'm sorry I didn't know Overflow was for researchers. Noted. | |
