[edit] Weak topology
The current version of the article states that:
- If X is a topological space with topology T, then the weak topology on X generated by C(X,S) coincides with T.
Is this true? I would say it holds only for T0-spaces. The 2-point indiscrete space could be a counterexample. --Kompik 18:56, 23 February 2006 (UTC)
- Surely for an indiscrete space (X,T), the weak topology on X generated by any set of continuous functions on X is still T, since the indiscrete topology is the weakest possible tolopogy on X. Martin Orr 21:43, 24 May 2006 (UTC)
