Truncated Painlevé expansion and a wide-ranging type of generalized variable-coefficient Kadomtsev-Petviashvili equations

Among the topics attracting much attention in mathematical physics are the variable-coefficient generalizations of the well-known Kadomtsev-Petviashvili equation (GVCKP). We show that the application of the truncated Painleve expansion and symbolic computation leads to a new class of analytical solutions to a wide-ranging type of GVCKPs, and an auto-Backlund transformation. The examples presented are solutions to the cylindrical Kadomtsev-Petviashvili equation and the nearly concentric Korteweg-de Vries equation.
