A short note on similarity of operator-valued multishifts
Soumitra Ghara, Surjit Kumar, Shailesh Trivedi
A complete characterization of the similarity between two operator-valued multishifts with invertible operator weights is obtained purely in terms of operator weights. This general…
Cesàro summability of Taylor series in higher order weighted Dirichlet type spaces
Soumitra Ghara, Rajeev Gupta, Md. Ramiz Reza
For a positive integer and a finite non-negative Borel measure on the unit circle, we study the Hadamard multipliers of higher order weighted Dirichlet-type spaces $\mathca…
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…
Summability and duality
Soumitra Ghara, Javad Mashreghi, Thomas Ransford
We formalize the observation that the same summability methods converge in a Banach space and its dual . At the same time we determine conditions under which these methods…
A local Douglas formula for higher order weighted Dirichlet-type integrals
Soumitra Ghara, Rajeev Gupta, Md. Ramiz Reza
We prove a local Douglas formula for higher order weighted Dirichlet-type integrals. With the help of this formula, we study the multiplier algebra of the associated higher order w…
