Definition
Let $\JJ_{ho}$ denote the collection of half-open intervals in $\R$.
Let $f: \R \to \R$ be a finite Stieltjes function.
The pre-measure of $f$ is the mapping $\mu_f: \JJ_{ho} \to \overline \R_{\ge 0}$ defined by:
- $\map {\mu_f} {\hointr a b} := \begin{cases}
\map f b - \map f a & \text{if } b \ge a \\ 0 & \text{otherwise} \end{cases}$
where $\overline \R_{\ge 0}$ denotes the set of positive extended real numbers.
