摘要
We study Hermitian kernels invariant under the action of a semigroup with involution. We characterize the Hermitian kernels that realize the given action by bounded operators on a Krein space. Applications include the GNS representation of *-algebras associated to Hermitian functionals and the dilation theory of Hermitian maps on C*-algebras.
