Abstract:A connected Tychonoff space $X$ is called maximal Tychonoff connected if there is no strictly finer Tychonoff connected topology on $X$. We show that if $X$ is a connected Tychonoff space and $Xin {$locally separable spaces, locally v{C}ech-complete spaces, first countable spaces$}$, then $X$ is not maximal Tychonoff connected. This result is new even in the cases where $X$ is compact or metrizable.

Keywords:Connected space   separable space   v{C}ech-complete space   first countable space   finer connected topology   maximal connected topology
