Abstract
We predict new features for the evolution of noncanonical screw wave-front
dislocations nested in diffracting light beams. The evolution equations for
the location of single-charge dislocations are derived, and their consequences
are elaborated by use of illustrative examples. It is shown that the dynamic
trajectories of the vortices can be controlled by adjustment of the noncanonical
strength of the input dislocations.
