Some Weighted Group Algebras are Operator Algebras
Abstract Let G be a finitely generated group with polynomial growth, and let ω be a weight, i.e. a sub-multiplicative function on G with positive values. We study when the weighted group algebra ℓ 1 ( G, ω ) is isomorphic to an operator algebra. We show that ℓ 1 …
