摘要：

We analyze a generalized Boussinesq equation using the theory of symmetry reductions of partial differential equations. The Lie symmetry group analysis of this equation shows that the equation has only a two-parameter point symmetry group corresponding to traveling-wave solutions. To obtain exact solutions, we use two procedures: a direct method and the G'/G-expansion method. We express the traveling-wave solutions in terms of hyperbolic, trigonometric, and rational functions.
