Pre-measure Pre-measure In mathematics, a pre-measure is a function that is, in some sense, a precursor to a "bona fide" measure on a given space. Indeed, one of the fundamental theorems in measure theory states that a pre-measure can be extended to a measure. Let "R" be a ring of subsets (closed under union and relative complement) of a fixed set "X" and let "μ": "R" → [0, +∞] be a set function. "μ" is called a pre-measure if and, for every countable (or finite) sequence {"A"} ⊆ "R" of pairwise disjoint sets whose union lies in "R", The second property
