Wold-type decomposition and Beurling-Type Theorem for Covariant Representations

Dimple Saini, Azad Rohilla

Using operator inequalities, we study a Wold-type decomposition of covariant representations. Building on this decomposition, we prove a Beurling-type theorem showing that every no…

Wold-type decomposition for doubly twisted left-invertible covariant representations

Niraj Kumar, Azad Rohilla, Harsh Trivedi

In this article, we have introduced the notion of a near-isometric covariant representation of a -correspondence. The other objective is to provide a unified approach to sever…

Ando type dilation for completely contractive covariant representations

Azad Rohilla, Dimple Saini

The central objective of this article is to investigate such isometric covariant representations that serve as dilations of completely contractive covariant representations.

Quantum -channels on -spaces

Priyabrata Bag, Azad Rohilla, Harsh Trivedi

If the symmetry, (an operator satisfying ) which defines the Krein space, is replaced by a (not necessarily self-adjoint) unitary, then we have the notion of an $…

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…
