摘要：

We study the effect of nonlinear gradient terms on localized states in a complex Ginzburg-Landau equation near a weakly inverted bifurcation. We find that these terms can greatly affect the speed of the state as well as cause an asymmetry. We also study the interaction of counterpropagating localized states in the coupled equations for counterpropagating waves. A comparison with recent experiments in binary fluid convection is made. © 1990.
