Texified, since problem was on front-page anyway

| Apr 15, 2011 at 17:10 | comment | added | Ostap Chervak | Every T_2 Lindelöf is normal. Even more, every Lindelöf is strongly paracompact hence paracompact hence normal. | |
| Dec 25, 2009 at 8:24 | comment | added | Guillermo Mantilla | I haven't had time to see your references yet but I like a lot the theorem you mention, and I also find it similar to the one in my question. About connections I'd ask, how far is T_2 and Lindelöf form normal? | |
