Timeline for Is there a name for the class of metric spaces such that the closure of the open ball of radius $r$ around each point $x$ is the set of elements $y$ such that $d(x,y)\leq r$ ?

| Sep 6, 2011 at 15:59 | comment | added | Emil Jeřábek | @Pietro: Out of curiosity: is it known which metric spaces have an equivalent distance function for which the property does hold? | |
| Sep 6, 2011 at 15:48 | comment | added | Pietro Majer | Note that every metric space that is not a single point has a uniformly equivalent distance for which that property does not hold, that is, a truncated distance $(x,y)\mapsto\min(d(x,y),r)$. Just to point out that it is really a property of the distance function. | |

fix typos, improve title
