Characterization of surjective isometries: the real case

Tianbao Guo, Jinghao Huang

Let $(Ω, μ)$ and $(Λ, λ)$ be complete atomless localizable semifinite measure spaces. Suppose that $E (Ω, μ)$ and $F (Λ, λ)$ are real rearrangement-invariant Banach function spaces with…

Isometric Structure in Noncommutative Symmetric Spaces

Kai Fang, Tianbao Guo, Jinghao Huang +1

This is a systematic study of isometries between noncommutative symmetric spaces. Let $M$ be a semifinite von Neumann algebra (or an atomic von Neumann algebra with all a…
