Some simple special Backlund transformation theorems are proposed and used to get explicit solutions of the BQGPV equation. Furthermore, all solutions of a second order linear ordinary differential equation including an arbitrary function can be used to construct explicit solutions of the (2+1)-dimensional BQGPV equation. Some figures are also given out to describe these solutions.展开更多
