Matrix liberation process III: Unitary Brownian motion and martingale analysis

Yoshimichi Ueda

We investigate the rate functions that emerge in our previous works towards large deviation principle for the matrix liberation process driven by the unitary Brownian motion as wel…

A remark on non-commutative -spaces

Shinya Kato, Yoshimichi Ueda

We explicitly describe the Haagerup and the Kosaki non-commutative -spaces associated with a tensor product von Neumann algebra in terms of those associa…

Lebesgue decomposition for positive operators revisited

Yoshiki Aibara, Yoshimichi Ueda

We explain how Pusz--Woronowicz's idea of their functional calculus fits the theory of Lebesgue decomposition for positive operators on Hilbert spaces initially developed by Ando.…

Spherical representations for -flows III: Weight-extended branching graphs

Yoshimichi Ueda

We apply Takesaki's and Connes's ideas on structure analysis for type III factors to the study of links (a short term of Markov kernels) appearing in asymptotic representation theo…

Spherical Representations of -Flows II: Representation System and Quantum Group Setup

Yoshimichi Ueda

This paper is a sequel to our previous study of spherical representations in the operator algebra setup. We first introduce possible analogs of dimension groups in the present cont…

Pusz--Woronowicz functional calculus and extended operator convex perspectives

Fumio Hiai, Yoshimichi Ueda, Shuhei Wada

In this article, we first study, in the framework of operator theory, Pusz and Woronowicz's functional calculus for pairs of bounded positive operators on Hilbert spaces associated…
