title: Characterization of phase singularities in the vector complex Ginzburg-Landau equation.
abstract: The vector complex Ginzburg-Landau equation is an amplitude equation appropriate for describing instabilities in oscillatory media when the order parameter is a vector field (for example, laser light or two-component Bose condensate). It is known that this equation presents a variety of phase singularities or topological defects. We study the parameters that characterize the different kinds of defects and show that the results are useful for a better understanding of the system dynamics.
