# The Travelling Wave Solutions of the Active-Dissipative Dispersive Media Equation by (*G*′/*G*)-Expansion Method

## Abstract

Over the past decades a number of approximate methods for finding travelling wave solutions to nonlinear evolution equations have been proposed. Among these methods, one of the current methods is so called (*G*′/*G*)-expansion method. In this paper, we will examine the (*G*′/*G*)-expansion method for determining the solutions of the active-dissipative dispersive media equation. The active-dissipative dispersive media equation is given by *μt* +*μμx* + *αμxx* + *βμxxx* + *γμxxxx* = 0, where for positive constants *α* and *γ* in equation are small-amplitude. This equation describe long waves on a viscous fluid flowing down along an inclined plane, unstable drift waves in plasma and stress waves in fragmented porous media. When *β* = 0, equation is reduced to the Kuramoto–Sivashinsky equation, which is the simplest equations that appears in modelling the nonlinear behaviour of disturbances for a sufficiently large class of active dissipative media. It represents the evolution of concentration in chemical reactions, hydrodynamic instabilities in laminar flame fronts and at the interface of two viscous fluids.
