摘要：

A multidimensional version of the derivative nonlinear Schrodinger equation is derived for long-wave-length periodic Alfven waves propagating in a plasma considered in the two-fluid approximation. It is shown that the coupling with magnetosonic waves takes the form of a mean drift which drastically affects the modulational stability of circularly polarized Alfven waves.
