| Aug 29, 2010 at 2:46 | comment | added | David Corwin | @Pete: So does your comment hold up that it is somehow related to the adelic topology on $GL_2$? | |

| Aug 26, 2010 at 16:48 | comment | added | Pete L. Clark | My first reaction is that this is related to the adelic topology on $GL_2$, although exactly how would require some further thought on my part. Probably someone else here will be able to follow up on this before I get back to it... | |
