摘要：Using gnomonic projection and Poincare model, we first define the spherical projection body and hyperbolic projection body in spherical space S^n and hyperbolic space H^n, then define the spherical Steiner symmetrization and hyperbolic Steiner symmetrization, finally prove the spherical projection inequality and hyperbolic projection inequality.
