Subharmonic bouncing solutions for a class of sublinear impact oscillators with indefinite weight
Subharmonic bouncing solutions for a class of sublinear impact oscillators with indefinite weight
In this paper, the existence and multiplicity of subharmonic bouncing solutions was considered for a class of sublinear Hill's type impact oscillators with indefinite weight. A series of canonical transformations were performed to verify the twist condition for Poincar$ \acute{e} $ map, then by applying Poincaré-Birkhoff twisted fixed point theorem, …
