Nonlinear maps preserving the mixed Jordan triple η-*-product between factors
Abstract
Let A and B be two factor von Neumann algebras and η be a non-zero complex number. A nonlinear bijective map φ: A→ B has been demonstrated to satisfy φ([A,B]*ηη C)=[φ(A),φ(B)]*ηηφ(C) for all A,B,C∈ A. If η=1, then φ is a linear *-isomorphism, a conjugate linear *-isomorphism, the negative of a linear *-isomorphism, or the negative of a conjugate linear *-isomorphism. If η≠ 1 and satisfies φ(I)=1, then φ is either a linear *-isomorphism or a conjugate linear *-isomorphism.
