| Abstract: | ![]()
We present a variational principle for small amplitude periodic solutions, with fixed frequency, of a completely resonant nonlinear wave equation. Existence and multiplicity results follow by min-max variational arguments.Supported by M.U.R.S.T. Variational Methods and Nonlinear Differential Equations. |
