Isometries of Haagerup--Schultz algebras

Jinghao Huang, Karimbergen Kudaybergenov, Fedor Sukochev +1

We establish a version of the classical results concerning descriptions of isometries on -algebras and noncommutative -spaces due to Kadison (1951) and Yeadon (1981) in t…

Characterizing convex trace ranges in finite atomic von Neumann algebras

A. Arziev, K. Kudaybergenov

The paper is devoted to characterizing convex trace ranges in finite atomic von Neumann algebras. The main result provides us with the necessary and sufficient condition for the ra…

Rank metric isometries and determinant-preserving mappings on II-factors

Jinghao Huang, Karimbergen Kudaybergenov, Fedor Sukochev

We fully describe the general form of a linear (or conjugate-linear) rank metric isometry on the Murray--von Neumann algebra associated with a II-factor. As an application, we…

Spectral Theorem for Self-Adjoint Partial Integral Operators in Kaplansky-Hilbert Modules

K. Kudaybergenov, A. Arziev, P. Orinbaev

In this paper, a spectral theorem is proved for self-adjoint cyclically compact partial integral operators in the space of functions with mixed norm, which is a Kaplansky--Hilbert…
