Extensions of isometric dual representations of semigroups

Let T be a dual representation of a suitable subsemigroup S of a locally compact abelian group G by isometrics on a dual Banach space X = (X*)*. It is shown that (X, T) can be extended to a dual representation of G on a dual Banach space Y containing X, and that this extension can be done in a canon...

description Let T be a dual representation of a suitable subsemigroup S of a locally compact abelian group G by isometrics on a dual Banach space X = (X*)*. It is shown that (X, T) can be extended to a dual representation of G on a dual Banach space Y containing X, and that this extension can be done in a canonical way. In the case of a representation by *-monomorphisms of a von Neumann algebra, the extension is a representation of G by *-automorphisms of a von Neumann algebra.
