A Variable Coefficient Version of Zakharov and Shabat’s Method: With Applications to the Integrationicient nonlinear equations. As an example, we show that if the variable coefficient b.(x,t) in their method satisfies the KdV equation ., then the nonlinear equation . is solvable through the inverse scattering transform by means of the extended procedure. We construct the one-soliton solution which
