| 摘 要： | <正>Maps on Positive Cones of C*-algebras Ming Chu GAO Gui Mei AN Abstract We prove that a surjective map (on the positive cones of unital C*-algebras)preserves the minimum spectrum values of harmonic means if and only if it has a Jordan*-isomorphism extension to the whole algebra.We represent weighted geometric mean preserving bijective maps on the positive cones of prime C*-algebras in terms of Jordan*-isomorphisms of the algebras.We also characterize orde... |
