| Feb 13, 2020 at 2:22 | comment | added | Bedovlat | The point is that, if the underlying space is not Hausdorff, a non-zero Borel measure can actually have empty support, which is sad. There is an example at the Wiki page referred to above in my question. Now whether or not that can happen in a standard Borel structure is the question. Thank you. | |

| Feb 12, 2020 at 23:13 | comment | added | Bedovlat | Is it better now? I am asking if such a measure can exist, or if it is excluded. It is excluded if $X$ is good enough, but all I have is $T_0$. | |

| Feb 12, 2020 at 23:11 | comment | added | Dieter Kadelka | Please clarify the assumptions. What if $X$ is Polish itself? Are you asking for an example of a $T_0$-space with the above property? | |
