Orthogonality preserving property, Wigner equation, and stability

Journal of Inequalities and Applications volume 2006, Article number: 76489 (2006) Cite this article

Abstract

We deal with the stability of the orthogonality preserving property in the class of mappings phase-equivalent to linear or conjugate-linear ones. We give a characterization of approximately orthogonality preserving mappings in this class and we show some connections between the considered stability and the stability of the Wigner equation.
