The Steinhaus-Weil property: its converse, subcontinuity and Solecki amenability
N. H. Bingham, A. J. Ostaszewski
The Steinhaus-Weil theorem that concerns us here is the simple, or classical, `interior-points' property -- that in a Polish topological group a non-negligible set B has the identi…

Beyond Lebesgue and Baire IV: Density topologies and a converse Steinhaus-Weil Theorem
N. H. Bingham, A. J. Ostaszewski
The theme here is category-measure duality, in the context of a topological group. One can often handle the (Baire) category case and the (Lebesgue, or Haar) measure cases together…

Effros, Baire, Steinhaus and Non-Separability
A. J. Ostaszewski
We give a short proof of an improved version of the Effros Open Mapping Principle via a shift-compactness theorem (also with a short proof), involving `sequential analysis' rather…
