Extract

Let G be a locally compact, unimodular, topological group with μ Haar measure on G, and μ* the corresponding inner measure. If (G) denotes the Borel subsets of G of finite measure, and V(G) = {μ(E):E(G)}, then the Product Set function, or P.S.-function, of the group G, written ΦG, is defined by
