Disjointness-preserving mappings on Calkin operator spaces and positive isometries
Kai Fang, Jinghao Huang, Karimbergen Kudaybergenov +1
The paper proves that any order‑measure continuous, disjointness‑preserving map between certain Calkin operator spaces over an atomless, finite semifinite von Neumann algebra must…

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…
