摘要: We study maps of positive operators the Schatten -classes (), which preserve -norms convex combinations, that is, . They are exactly those carrying form for a unitary or antiunitary In case , we have same conclusion whenever it just holds all Hilbert-Schmidt class norm Some examples demonstrated.
