Abstract

Stone's theorem states that "A bounded linear operator A is infinitesimal generator of a <TEX>$C_0$</TEX>-group of unitary operators on a Hilbert space H if and only if iA is self adjoint". In this paper we establish a generalization of Stone's theorem in the framework of Hilbert <TEX>$C^*$</TEX>-modules.
