| May 29, 2013 at 18:12 | comment | added | Henno Brandsma | It's customary in generalised metric spaces to assume at least $T_3$ ($T_1$ plus regular). This is also customary for stratifiable and semi-stratifiable spaces, AFAIK. | |

| May 29, 2013 at 11:40 | comment | added | Paul | $g: \mathbb N \times X \to \tau_X$ is a $g$-function of $X$ if for any $x$ and $n \in \mathbb N$, $x \in g(n+1,x) \subset g(n,x)$. | |
