| Feb 21, 2012 at 6:08 | comment | added | Julie | @ David and Yoav. Ah, thanks. I have updated my additional info. | |
| Feb 21, 2012 at 4:46 | comment | added | David Feldman | BTW, I don't understand your "Additional info." An open set doesn't contain its boundary?!? Right? | |
| Feb 21, 2012 at 4:45 | comment | added | David Feldman | $R^{mxn}$ is $\sigma$−compact so an uncountable open cover has a countable subcover. So you're good, right? | |
| Feb 21, 2012 at 4:38 | comment | added | Yoav Kallus | Your additional info imply that $A_j$ is an open set which contains its boundary, making it closed. Did you mean to write that $A_j$ is the closure of an open set? | |

| Feb 21, 2012 at 1:51 | comment | added | user9072 | If you allow uncountably many sets just to get what you claim you could make the Ah's singletons. So, by itself this cannot possibly tell much. I am afraid without further details there is not much specufuc to answer. | |
