چکیده
|
It is shown that a space x is basically disconnected if and only if x is countably basically disconnected and strongly zero-dimensional. we observ that x is countably basically disconnected if and only if beta_0x is countably basically disconnected (basically disconnected) and x is extermally disconnected ifand only if beta_0x is extermally disconnected. we prove that x is extermally disconnected if and only if very dense (open) subspace in x, is c^f-embedded in x
