论文摘要
作为计划的一部分，引入了$ bv（σ）$和$ ac（σ）$的空间$（σ）$（σ）$，该计划找到了一个涵盖良好的操作员和在Banach空间上行动的良好的三角经营者。自从他们最初的出现以来，很明显可以简化这些定义。 在本文中，我们使用这种简化的方法对这些空间的主要特性进行了独立的说明。
The spaces $BV(σ)$ and $AC(σ)$ 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.
