Definition
Let $d \in \N$.
Let $\map \BB {\R^d}$ be the Borel $\sigma$-algebra on $\R^d$.
Let $\lambda$ be the Lebesgue measure on $\struct {\R^d, \map \BB {\R^d} }$.
Let $\mu$ be a measure, signed measure or complex measure on $\struct {\R^d, \map \BB {\R^d} }$.
We say that $\mu$ is singular if and only if $\mu$ and $\lambda$ are mutually singular measures.
