Multisoliton solutions of the (2+1)-dimensional KdV equation

Using the extension homogeneous' balance method, we have obtained some new special types of soliton solutions of the (2+1) -dimensional KdV equation. Starting from the homogeneous balance method, one can obtain a nonlinear transformation to simple (2+1) -dimensional KdV equation into a linear partial differential equation and two bilinear partial differential equations. Usually, one can obtain only a kind of soliton-like solutions. In this letter, we Find further some special types of the multisoliton solutions from the linear and bilinear partial differential equations.
