Category-measure duality: convexity, mid-point convexity and Berz sublinearity

N. H. Bingham, A. J. Ostaszewski

Category-measure duality concerns applications of Baire-category methods that have measure-theoretic analogues. The set-theoretic axiom needed in connection with the Baire category…

Homomorphisms from Functional Equations: The Goldie Equation

Adam J. Ostaszewski

The theory of regular variation, in its Karamata and Bojanić-Karamata/de Haan forms, is long established and makes essential use of the Cauchy functional equation. Both forms are s…

Cauchy's functional equation and extensions: Goldie's equation and inequality, the Gołąb-Schinzel equation and Beurling's equation

N. H. Bingham, A. J. Ostaszewski

The Cauchy functional equation is not only the most important single functional equation, it is also central to regular variation. Classical Karamata regular variation involves a f…

Kingman, category and combinatorics

N. H. Bingham, A. J. Ostaszewski

Kingman's Theorem on skeleton limits---passing from limits as n→∞ along nh (n∈N) for enough h>0 to limits as t→∞ for t∈R---is…
