But the OPs questions have had so little context that I don't feel good about answering them, as they look like the kind of HW questions one gets in a good graduate course on general topology. | |

| Oct 18, 2011 at 12:02 | comment | added | David White | I thought about this some more and was trying to come up with a space like I describe above via an uncountable discrete topology. This won't work as stated because the discrete topology is metrizable, hence first countable. However, a 1-point compactification might work. I think the problem now has been reduced to looking in Counterexamples in Topology | |
