Abstract:

In this paper Wronskian solutions of the KP equation are discussed via a modified bilinear Bäcklund transformation. The conditions that the Wronskian entries satisfy are obtained and the Wronskian verification is achieved by means of the Wronskian technique. Finally, some explicit Wronskian entries are given.

Key words: bilinear form, modified Bä, Wronskian solution, cklund transformation, KP equation
