Twisted Representations of Product Systems of $$C^*$$-Correspondences: Wold Decomposition and Unitary Extensions

Abstract We investigate Wold-type decompositions and unitary extension problems for multivariable isometric covariant representations associated with product systems of $$C^*$$ C ∗ -correspondences. First, we establish an operator-theoretic characterization for the existence of a...
