Talk:Second-countable space

From Wikipedia, the free encyclopedia

[edit] Counterexample

I think it would be nice to add to the Introduction an example of a topological space that isn't second countable.

• Just take with the discrete topology. A less trivial example would be an uncountable disjoint union of any space with at least one non-trivial open set. Albmont (talk) 22:02, 9 April 2008 (UTC)
