Notes:
A set of coupled nonlinear differential equations which govern the dynamics of low-frequency short-wavelength electromagnetic waves in a nonuniform magnetized electron–positron (pair) plasma with dust has been derived. In the linear limit, a local dispersion relation has been derived and analyzed. It is shown that in the absence of density gradients and equilibrium sheared plasma flow, can make the dust shear Alfvén waves unstable. In the nonlinear case, the temporal behavior of nonlinear dissipative system can be expressed in the form of well known Lorenz and Stenflo type equations that admit chaotic trajectories. On the other hand, a quasi-stationary solution of the mode coupling equations can be represented in the form of dipolar and vortex-chain solutions. The results of our present investigation should be helpful for understanding plasma transport and wave phenomena in the pulsars magnetosphere. © 2000 American Institute of Physics.
