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 $…
