JakobianFor definitions of extremally disconnected, $P$-space, basically disconnected (under the name $\sigma$-complete), $F$-spaces, $F'$-spaces, and relations between them, see [3]. A dense subspace of extremally disconnected space is extremally disconnected. This fails horribly for basically disconnec...
