NONLINEAR STABILITY OF THE PERIODIC TRAVELING WAVE SOLUTION FOR A CLASS OF COUPLED KDV EQUATIONS

In this paper, by applying the Jacobian ellipse function method, we obtain a click here group of periodic traveling wave solution of coupled KdV equations.Furthermore, by the implicit function theorem, the relation between some wave velocity and the read more solution’s period is researched.Lastly, we show that this type of solution is orbitally
