The Backlund transformation method of Riccati equation to coupled Higgs field and Hamiltonian amplitude equations

In this paper, we establish new exact solutions for some complex nonlinear wave equations. The Backlund transformation method of Riccati equation is used to construct exact solutions of the Hamiltonian amplitude equation and the coupled Higgs field equation. This method presents a wide applicability to handling nonlinear wave equations. These equations play a very important role in mathematical physics and engineering sciences. Obtained solutions may also be important of significance for the explanation of some practical physical problems.
