摘要: Abstract The propagation of soliton pulses in an inhomogeneous media that is described by a K ( m , n ) equation with t-dependent coefficients studied. By using solitary wave ansatz the form sech p and tanh functions, respectively, we obtain exact bright dark solutions for considered model. All physical parameters are obtained as functions varying model coefficients. Such may be useful to explain dynamics nonlinear systems exhibiting dispersive effects. Parametric conditions formation determined.
