A particle that is constrained to freely move on a hyperspherical surface in an dimensional flat space experiences a curvature-induced gauge potential, whose form was given long ago (Ohnuki and Kitakado, 1993). We demonstrate that the momentum for the particle on the hypersphere is the geometric one including the gauge potential and its components obey the commutation relations , in which is the Planck’s constant, and () denotes the -th component of the geometric momentum, and specifies the -th component of the generalized angular momentum containing both the orbital part and the coupling of the generators of continuous rotational symmetry group and curvature, and denotes the radius of the dimensional hypersphere.
