Abstract
The spaces \(BV(\sigma )\) and \(AC(\sigma )\) were introduced as part of a program to find a general theory which covers both well-bounded operators and trigonometrically well-bounded operators acting on a Banach space. Since their initial appearance it has become clear that the definitions could be simplified somewhat. In this paper we give a self-contained exposition of the main properties of these spaces using this simplified approach.

Data sharing not applicable to this article as no datasets were generated or analysed during the current study.
Notes
In most later proofs we shall not explicitly consider this possibility. The diligent reader will check that that statements are typically trivially true for lists with just one element.
