Doubly Commuting Semigroups of Isometries

C. H. Namitha, S. Sundar, Shankar Veerabathiran

In this paper, we discuss the structure of doubly commuting semigroups of isometries. We record a new proof of Cooper's theorem in the Hilbert module setting. We discuss the Fell t…

Powers and roots of partial isometric covariant representations

Dimple Saini, Harsh Trivedi, Shankar Veerabathiran

Isometric covariant representations play an important role in the study of Cuntz-Pimsner algebras. In this article, we study partial isometric covariant representations and explore…

A characterization of invariant subspaces for isometric representations of product system over

Dimple Saini, Harsh Trivedi, Shankar Veerabathiran

Using the Wold-von Neumann decomposition for the isometric covariant representations due to Muhly and Solel, we prove an explicit representation of the commutant of a doubly commut…

Beurling quotient subspaces for covariant representations of product systems

Azad Rohilla, Harsh Trivedi, Shankar Veerabathiran

We characterize Beurling quotient subspaces for pure doubly commuting isometric representations of product systems. As a consequence, we derive a concrete regular dilation theorem…

Regular covariant representations and their Wold-type decomposition

Azad Rohilla, Harsh Trivedi, Shankar Veerabathiran

Olofsson introduced a growth condition regarding elements of an orbit for an expansive operator and generalized Richter's wandering subspace theorem. Later on, using the Moore-Penr…

Generating wandering subspaces for doubly commuting covariant representations

Harsh Trivedi, Shankar Veerabathiran

We obtain a Halmos-Richter-type wandering subspace theorem for covariant representations of C*-correspondences. Further the notion of Cauchy dual and a version of Shimorin's Wold-t…

Doubly commuting invariant subspaces for representations of product systems of -correspondences

Harsh Trivedi, Shankar Veerabathiran

We obtain a Shimorin-Wold-type decomposition for a doubly commuting covariant representation of a product system of -correspondences. This extends a recent Wold-type decomposi…
