Equations of motion for the vortices of the two-dimensional Gross-Pitaevskii(2dGP) and Higgs (2dH) equations are derived with use of the Lagrangian formula-tion. The relation between symmetry properties and conservation laws for the vortexsolutions are discussed. We observe numerical evidence of the chaotic behaviors offew vortex systems. This indicates that the 2dGP and 2dH equations arenonintegrable.
