Bitopology and measure-category duality
N. H. Bingham and A. J. Ostaszewski
We re-examine measure-category duality by a bitopological approach, using both the Euclidean and the density toplologies of the line. We give a topological result (on convergence of homeomorphisms to the identity) obtaining as a corollary results on infinitary combinatorics due to Kestelman and to Borwein and Ditor. As a by-product we give a unified proof of the measure and category cases of Uniform Convergence Theorem for slowly varying functions.A PDF file (144 kB) with the full contents of this report can be downloaded by clicking here.
