Failure of noncommutative Rota's theorem with $L lo g L$ endpoint

Hiranmoy Ghorui, Suman Mondal, Samya Kumar Ray

We construct a factorizable Markov map $T$ on a hyperfinite finite von Neumann algebra and a positive element $x \in L lo g L$ for which the sequence $T^{n} (T^{*})^{n} x$ does not converge…

Maximal Ergodic Theorems for Operators with Finite Peripheral Spectrum

Subhajit Palai, Samya Kumar Ray

Let $M$ be a semifinite von Neumann algebra and $T : M \to M$ be a positive $L_{\infty} - L_{1}$ contraction in the sense of Junge-Xu, of which the numerical…

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 $G$ be a connected simple Lie group of real rank one and finite center, and let $K$ be a maximal compact subgroup. We study the families of spherical, ball, and uniform average…

Maximal ergodic inequalities for some positive operators on noncommutative $L_{p}$ -spaces

Guixiang Hong, Samya Kumar Ray, Simeng Wang

In this paper, we establish the one-sided maximal ergodic inequalities for a large subclass of positive operators on noncommutative $L_{p}$ -spaces for a fixed $1 < p < \infty$ , which par…
