Abstract

A Hausdorff topological group topology on a group GG is the minimum (Hausdorff) group topology if it is contained in every Hausdorff group topology on GG. For every compact metrizable space XX containing an open nn-cell, n2n\ge2, the homeomorphism group H(X)H(X) has no minimum Hausdorff group topology. The homeomorphism groups of the Cantor set and the Hilbert cube have no minimum group topology. For every compact metrizable space XX containing a dense open one-manifold, H(X)H(X) has the minimum group topology. Some, but not all, oligomorphic groups have the minimum group topology.
