Abstract:
We study the vortex trajectories for the two-dimensional complex parabolic Ginzburg-Landau equation without well-preparedness assumption. We prove that the trajectory set is rectifiable, and satisfies a weak motion law. In the case of degree $\pm 1$ vortices, the motion law is satisfied in the classical sense. Moreover, dissipation occurs only at a finite number of times. Away from these times, possible collisions and splittings of vortices are constrained by algebraic equations involving their topological degrees.
Quantization properties of the energy and potential densities play a central role in the proofs.
