Abstract

Let HH and HH' be a complex Hilbert spaces. For p(1,)\{2}p\in(1, \infty)\backslash\{2\} we consider the Banach space Cp(H)C_p(H) of all pp-Schatten von Neumann operators, whose unit sphere is denoted by S(Cp(H))S(C_p(H)). We prove that every surjective isometry Δ:S(Cp(H))S(Cp(H))\Delta: S(C_p(H))\to S(C_p(H')) can be extended to a complex linear or to a conjugate linear surjective isometry T:Cp(H)Cp(H)T:C_p(H)\to C_p(H').
