Ortho-isomorphisms of von Neumann algebras

Minghui Ma, Weijuan Shi

Suppose $M$ and $N$ are von Neumann algebras. Two operators $A$ and $B$ in $M$ are said to be orthogonal if $A^{*} B = 0$ , meaning their ranges are orthogonal…

Surjective $L^{p}$ -isometries of Grassmann spaces

Wenhua Qian, Junhao Shen, Weijuan Shi +2

Based on the characterization of surjective $L^{p}$ -isometries of unitary groups in finite factors, we describe all surjective $L^{p}$ -isometries between Grassmann spaces of projection…
