摘要: Nonlinear Alfven waves, propagating along a homogeneous magnetic field, are studied using relativistic isotropic hydrodynamics. solitons of the moving-wave and wave packet types considered for modified Korteweg–de Vries (mKdV) equation nonlinear Schrodinger (NLS) equation, respectively. The method characteristics is used Backlund transformations (BTs) employed to generate new solutions from old ones. Thus, families mKdV NLS equations obtained. question arises which exist in pulsar atmosphere.
