We present a KdV-like 2-parameter equation u t + (3(1 − δ)u + (δ + 1) uxx ux)u x = ϵu xxx. By using the dynamical system method, existence of different traveling wave solutions are discussed, including smooth solitary wave solution of with bell type, solitary wave solutions of valley type and peakon wave solution of valley type. Numerical integration are(More)
Lattice models are associated with rather important problems in physics. Solution of these models gives insights into the nature of phase transitions, magnetization and scaling behavior, as well as insights into the nature of quantum field theory. An expanded G'/G-expansion method is presented to seek explicit solutions of nonlinear lattice equations. The(More)
