Dirichlet-type spaces of the bidisc and Toral -isometries
Santu Bera, Sameer Chavan, Soumitra Ghara
We introduce and study Dirichlet-type spaces of the unit bidisc where are finite positive Borel measures on the unit circle. We sho…
Convergence of power sequences of B-operators with applications to stability
Sameer Chavan, Zenon Jan Jabłoński, Il Bong Jung +1
The B-operators (abbreviation for Brownian-type operators) are upper triangular 2x2 block matrix operators that satisfy certain algebraic constraints. The purpose of this paper is…
Lifting Brownian-type operators with subnormal entry
Sameer Chavan, Zenon Jan Jablonski, Il Bong Jung +1
In this paper, we study Brownian-type operators, which are upper triangular block matrix operators with entries satisfying some algebraic constraints. We establish a li…
Bi-isometries reducing the hyper-ranges of the coordinates
Sameer Chavan, Md. Ramiz Reza
Let be a bi-isometry, that is, a pair of commuting isometries and on a complex Hilbert space By the von Neumann-Wold decomposition, the hyper…
Multishifts on Directed Cartesian Product of Rooted Directed Trees
Sameer Chavan, Deepak Kumar Pradhan, Shailesh Trivedi
We systematically develop the multivariable counterpart of the theory of weighted shifts on rooted directed trees. Capitalizing on the theory of product of directed graphs, we intr…
