[Banach] Abstract of a paper by Harald Hanche-Olsen and Helge Holden

This is an announcement for the paper "The Kolmogorov-Riesz compactness theorem" by Harald Hanche-Olsen and Helge Holden.

Abstract: We show that the Arzela-Ascoli theorem and Kolmogorov compactness theorem both are consequences of a simple lemma on compactness in metric spaces. Their relation to Helly's theorem is discussed. The paper contains a detailed discussion on the historical background of the Kolmogorov compactness theorem.
