摘要: When solving systems of PDE with two space dimensions it is often assumed that the solution spatially doubly periodic. This assumption usually made in such as Boussinesq equation or reaction-diffusion equations where have Euclidean invariance. In this article we use group theoretic techniques to determine a large class periodic solutions are forced existence near steady-state bifurcation from translation-invariant equilibrium.
