Projective representations of the inhomogeneous Hamilton group: Noninertial symmetry in quantum mechanics

► Projective representations of the inhomogeneous Hamilton group. ► Unitary representations of groups with Weyl-Heisenberg normal subgroup using Mackey theorems. ► Physical interpretation of the Hamilton group as a local noninertial symmetry of the Hamilton equations. ► Automorphism group of the Weyl-Heisenberg group defines the maximal quantum mechanical symmetry. ► Projective representations of the inhomogeneous Hamilton group: noninertial quantum symmetry.
