%0 Journal Article %J Frontiers of Mathematics in China %D 2008 %T Cantor families of periodic solutions for completely resonant wave equations %A Massimiliano Berti %A Philippe Bolle %X We present recent existence results of Cantor families of small amplitude periodic solutions for completely resonant nonlinear wave equations. The proofs rely on the Nash-Moser implicit function theory and variational methods. © 2008 Higher Education Press. %B Frontiers of Mathematics in China %V 3 %P 151-165 %G eng %R 10.1007/s11464-008-0011-3
