摘　　要：The existence of Mather sets(generalized quasiperiodic solutions and uNlinked periodicsolutions)for sublinear Duffing equations is shown. Here the approach is based on the use ofaction-angle variables and the application of a generalized version of Aubry-Mather theoremon semi-cylinder with finite twist assumption.

关 键 词：Sublinear Duffing equation Finite twist Aubry-Mather theorem Mather sets.
