Physics Theoretical physics Rotational symmetry Phase (waves)Order (ring theory)Gravitational singularity Physical optics Optical vortex Action (physics)Topological quantum number

description

We present a study of the dynamics and decay pattern of phase singularities due to the action of a system with a discrete rotational symmetry of finite order. A topological charge conservation rule is identified.
