Let G and H be locally compact groups with continuous weights ω1 and ω2 respectively, such that 0f25365bb9e34911ac8d6782dee" title="Click to view the MathML source">ωi(ei)=1, i=1,2. In this article we show that if M(G,ω1) (the weighted measure algebra on G ) is isometrically algebra isomorphic to M(H,ω2), then the underlying weighted groups are isomorphic, i.e. there exists an isomorphism of topological groups ϕ:G→H such that is multiplicative. Similarly, we show that any weighted locally compact group (G,ω) is completely determined by its Beurling group algebra 70ff3" title="Click to view the MathML source">L1(G,ω), LUC(G,ω−1)⁎ and L1(G,ω)⁎⁎, when the two last algebras are equipped with an Arens product.
