Added some thoughts.

| Jun 20, 2010 at 9:03 | comment | added | Matthew Daws | A further thought: the map $\pi$ can be thought of as $C(\beta H)\rightarrow C(\beta G)$ and is hence associated to some continuous map $\tilde\theta:\beta G\rightarrow\beta H$. Now, it's pretty easy to see that $\pi$ is surjective if and only if $\tilde\theta$ is injective. Furthermore, $\tilde\theta$ extends $\theta$. So, is it possible for $\theta$ to inject without closed range, and for $\tilde\theta$ to inject? | |
