The Set of Universal Interpolating Functions is Nowhere Dense

General Topology 2026-02-09 v1

Abstract

In 1998, Benyamini introduced and proved the existence of universal interpolating functions. In the note we prove that the set of universal interpolating functions is nowhere dense in the space of continuous functions on R\mathbb{R}. Several extensions and generalisations are also considered.
