Correction: “The set of continuous nowhere differentiable functions”

R. Daniel Mauldin

Vol. 121 (1986), No. 1, 119–120
Abstract

Let M be the set of all continuous real-valued functions defined on the closed unit interval [0,1] which do not have a finite derivative anywhere. The purpose of this note is to complete the argument that M is a coanalytic set and is not a Borel set by correcting an error in the last paragraph of an earlier paper on this topic.
