摘要：
We prove the existence of periodic solutions in a class of nonlinear partial differential equations, including the nonlinear Schrodinger equation, the nonlinear wave equation, and the nonlinear beam equation, in higher dimension. Our result covers cases of completely resonant equations, where the bifurcation equation is infinite-dimensional, such as the nonlinear Schrodinger equation with zero mass, for which solutions which at leading order are wave packets are shown to exist.
