We study the compactification of the Wallman-Shanin type of T0
-spaces. We have introduced the notion of compressed compactification and proved that any compressed compactification is of the Wallman-Shanin type. The problem of the
validity of the equality ω(X
) = ωX
is examined. Two open questions have arisen.
