| Abstract: | We concentrate on finding exact solutions for a generalized variable-coefficient Korteweg--de Vries equation of physically significance. The analytic N-soliton solution in Wronskian form for such a model is postulated and verified by direct substituting the solution into the bilinear form by virtue of the Wronskian technique. Additionally, the bilinear auto-Bäcklund transformation between the (N-1)- and N-soliton solutions is verified. |
