The decomposable and the ambiguous sets
We prove that every ambiguous subset of a hereditarily Bairespace is decomposable. We obtain that a decomposable set$Asubseteq X$ is ambiguous when (i) $X$ is a perfectlyparacompact space, or (ii) $A$ and $Xsetminus A$ are Lindel"{o}fand $X$ is a completely regular space.
