Abstract
If ϕ is a surjective isometry of the separable symmetric operator spaceE(M, τ) associated with the approximately finite-dimensional semifinite factorM and if ∥·∥ E(M,τ) is not proportional to ∥·∥ L 2, then there exist a unitary operatorU∈M and a Jordan automorphismJ ofM such thatϕ(x)=UJ(x) for allx∈M∩E(M, τ). We characterize also surjective isometries of vector-valued symmetric spacesF((0, 1), E(M, τ)).
