On Joint Functional Calculus For Ritt Operators
Parasar Mohanty, Samya Kumar Ray
In this paper, we study joint functional calculus for commuting -tuple of Ritt operators. We provide an equivalent characterisation of boundedness for joint functional calculus…
On Functional Calculus For -Ritt operators
Samya Kumar Ray
In this paper, we present a new class of operators, which we name to be -Ritt operators. This produces a discrete analogue of -sectorial operators and generalizes the notion…
On Multivariate Matsaev's Conjecture
Samya Kumar Ray
In this article, we study multivariate generalizations of the Matsaev's conjecture in commutative and non-commutative -spaces.We prove that the multivariate analogue of Matsae…
Contractivity vs. Complete Contractivity via property P
Samya Kumar Ray
In this paper, we consider the question of contractivity vs. complete contractivity for domains in , which are unit balls with respect to some norm. We show that for…
