Lamperti Operators, Dilation Theory, and Applications in Noncommutative Ergodic Theory
Guixiang Hong, Wei Liu, Samya Kumar Ray +1
In this paper, we develop a novel framework for quantitative mean ergodic theorems in the noncommutative setting, with a focus on actions of amenable groups and semigroups. We prov…
Noncommutative ergodic theorems for action of semisimple Lie groups
Guixiang hong, Samya Kumar Ray
Let be a connected simple Lie group of real rank one and finite center, and let be a maximal compact subgroup. We study the families of spherical, ball, and uniform average…
On Isometric Embedding and Unique operator space structure
Samya Kumar Ray
We study existence of linear isometric embedding of into for and unique operator space structure on two dimensional Banach spaces. For $p\i…
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…
