Moment measure

where $\backslash textstyle\; B\; 1,...,B\; n$ is a collection of not necessarily disjoint Borel sets (in $\backslash textstyle\; \backslash textbf\{R\}^\{\; d\}$), which form a $\backslash textstyle\; n$-fold Cartesian product of sets denoted by $B\; 1\backslash times,\backslash dots,\backslash times\; B\; n$.
