Abstract
Two coupled nonlinear equations for a perturbed electromagnetic field in an electron-positron streaming plasma which is placed in a nonuniform magnetic field are derived and solved analytically, yielding stationary solutions in the form of vortices consisting of monopolar and quadrupolar parts. It is shown that vortices are created in and carried by a specific given linens shear flow profile and a given nonuniformity of the magnetic shear. (C) 2000 American Institute of Physics.
