Timeline for If $(X,\tau)$ has more than $1$ point and is $T_2$ and connected, do we have $|X| =|\tau|$?

May 21, 2018 at 17:23 | comment | added | Ashutosh | No problem. The following may be interesting: (1) Does the density topology on $\mathbb{R}^n$ (for $n \geq 2$) preserve old connected sets? (2) If not, is there another topoogy $\tau$ on $\mathbb{R}^n$ ($n \geq 2$) that refines the usual topology, has size $2^{\mathfrak{c}}$ and preserves old connected sets. | |
