• A new method of perturbation for the study of nonlinear wave propagation in amagnetoplasma is proposed under the condition that the dielectric tensor of theplasma changes slowly in time and space. Using this method, we derive a generalizednonlinear wave equation for the transverse waves propagating along magnetic fieldlines, which includes the effects due to the ponderomotive force or due to an inhomogeneity of the plasma. The physical condition is elucidated for the wave-trap-ping in two- or three-dimensional space which comes from a negative-pressure effectof the ponderomotive force or the inhomogeneity.plasma waves, nonlinear wave effects, nonlinear wave-trapping
