Homework Statement
Let X be a first countable space where no sequence has more than one limit. Show that X must be Hausdorff.
Homework Equations
The Attempt at a Solution
Hi everyone,
Here's what I've done so far:
I used this thm: If X is a Hausdorff space, then sequences in X can have at most one limit. (but not necessarily the converse)
So X is potentially a Hausdorff space as all it's sequences have only one limit, if at all.
But then I'm completely stuck as to where to go from here. Obviously it's got something to do with being first countable, but I can't see what! Can anyone please give me a point in the right direction?
Thanks for any help!
