    This paper studies properties of \(\alpha\)-Hausdorff subsets, almost closed mappings and almost upper semicontinuous decompositions. The theorems provide conditions which show when certain subsets of a topological space can be separated by open sets. They also provide conditions which show when functions are continuous or closed.
