On some functional equations related to bicircular projections

Recently, the question of determining the structure of (generalized) bicircular projections on a given Banach space has drawn attention of a number of mathematicians from different points of view. It turns out that every generalized bicircular projection acting on a JB*-triple satisfies a certain functional equation, which enables to determine the structure of these mappings. The main result is applied to C*-algebras.
