Some remarks on Reduced -algebras of semigroup dynamical systems and product systems

Md Amir Hossain, S. Sundar

We study the exactness of the reduced crossed product of a semigroup dynamical system and the reduced -algebra of a product system. We show that for a semigroup dynamical sy…

Multiparameter Decomposable Product Systems

C. H. Namitha, S. Sundar

In [8], Arveson proved that a -parameter decomposable product system is isomorphic to the product system of a CCR flow. We show that the structure of a generic decomposable prod…

Examples of Multiparameter CCR flows with non-trivial index

Piyasa Sarkar, S. Sundar

In this paper, we construct uncountably many examples of multiparameter CCR flows, which are not pullbacks of -parameter CCR flows, with index one. Moreover, the constructed CCR…
