Query: Fixed points of reflections of compact convex sets and a
  characterization of state spaces of Jordan Banach algebras   In the present article we prove a fixed point theorem for reflections of
compact convex sets and give a new characterization of state space of
JB-algebras among compact convex sets. Namely they are exactly those compact
convex sets which are strongly spectral and symmetric.
