Abstract
If H is a Hilbert space, φ is a (not necessary linear) -surjective mapping on B(H ) and φ preserves the spectrum of operators of the form ABA, then φ is either an algebra automorphism or an algebra anti-automorphism.
Keywords
, Spectrum, rank one operator, trace functional, operator algebra, auto- morphism, anti-automorphism.
