] | The claim about Esperanto having [propedeutic](http://en.wiktionary.org/wiki/propaedeutic) properties for French learners comes from the EKPAROLI project, you can find a somewhat outdated but [detailed report](http://web.archive.org/web/20031204061223/http://www.education.monash.edu.au/projects/esperanto/Ekrep97.htm) a... | (Apologies, I'm writing this comment in a way so that even passersby who have zero knowledge of Esperanto can make more sense of it)
As for the research, honestly there's quite a few very easily findable online, especially via Wikipedia reference links on various pages related to Esperanto. The "open library" has a fe... |
2,019,390 | For a **locally compact abelian** (LCA) group $G$ let $\hat{G}$ denotes the dual group (the group of characters on $G$). Now with the compact open topology $\hat{G}$ becomes a LCA group. I need to prove the following -
1) $\hat{\mathbb{Z}} \cong \mathbb{S}^1$
2) $\hat{\mathbb{S}}^1 \cong \mathbb{Z}$
3) $\hat{\mathb... | 2016/11/18 | [

] | This is very basic. The first isomorphism is almost tautological:
$\hat{\mathbb{Z}}$ is the group of (continuous) homomorphisms $\mathbb{Z}\to\mathbb{S}^1$ and this is algebraically and topologically isomorphic to $\mathbb{S}^1$.
