Extreme points, positive Grothendieck constants and tensor product norms
Rajeev Gupta, Arpita Mal, Gadadhar Misra +1
We study several interrelated problems arising from the interplay between extreme point theory, Grothendieck-type inequalities, and tensor product norms. We develop a general frame…
On a variant of the Grothendieck inequality and estimates on tensor product norms
Rajeev Gupta, Gadadhar Misra, Samya Kumar Ray
We investigate a Grothendieck-type inequality for pairs of Banach spaces assuming is finite-dimensional and study the associated Grothendieck-type constant. We prove that…
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…
Dirichlet-type spaces on the unit ball and joint 2-isometries
Sameer Chavan, Rajeev Gupta, Md. Ramiz Reza
We obtain a formula that relates the spherical moments of the multiplication tuple on a Dirichlet-type space to a complex moment problem in several variables. This can be seen as t…
Unitary equivalence of operator-valued multishifts
Rajeev Gupta, Surjit Kumar, Shailesh Trivedi
We systematically study various aspects of operator-valued multishifts. Beginning with basic properties, we show that the class of multishifts on the directed Cartesian product of…
Weighted Join Operators on Directed Trees
Sameer Chavan, Rajeev Gupta, Kalyan B. Sinha
A rooted directed tree with can be extended to a directed graph by adding a vertex to and declaring each v…
