Popis: Let be the space of complex matrices, and for a nonzero vector and , let denote the local spectrum of T at e. Characterizations are obtained for maps on satisfying where the binary operation stands for the skew Jordan semi-triple product or the skew product on matrices, with no additional assumption on the range of the map .
