Abstract

A Boolean algebra \A\A equipped with a (finitely-additive) positive probability measure mm can be turned into a metric space (\A,dm)(\A , d_{m}), where dm(a,b)=m((a¬b)(¬ab))d_{m}(a,b)= m ((a\wedge\neg b)\vee(\neg a\wedge b)), for any a,bAa,b\in A, sometimes referred to as \emph{metric Boolean algebra}. In this paper, we study under which conditions the space of atoms of a finite metric Boolean algebra can be isometrically embedded in RN\mathbb{R}^{N} (for a certain NN) equipped with the Euclidean metric. In particular, we characterize the topology of the positive measures over a finite algebra \A\A such that the metric space (At(\A),dm)(\mathsf{At}(\A), d_m) embeds isometrically in RN\mathbb{R}^{N}.
