Singular measure Singular measure In mathematics, two positive (or signed or complex) measures "μ" and "ν" defined on a measurable space (Ω, Σ) are called singular if there exist two disjoint sets "A" and "B" in Σ whose union is Ω such that "μ" is zero on all measurable subsets of "B" while "ν" is zero on all measurable subsets of "A". This is denoted by formula_1 A refined form of Lebesgue's decomposition theorem decomposes a singular measure into a singular continuous measure and a discrete measure. See below for examples. As a particular case, a measure defined on the Euclidean space
