Manifolds: Hausdorffness versus homogeneity
Mathieu Baillif, Alexandre Gabard · Proceedings of the American Mathematical Society · 2007
We analyze the relationship between Hausdorffness and homogeneity in the frame of manifolds not confined to be Hausdorff. We exhibit examples of homogeneous non-Hausdorff manifolds and prove that a Lindelöf homogeneous manifold is Hausdorff.
