Periodic bouncing solutions for Hill's type sub-linear oscillators with obstacles
<p style='text-indent:20px;'>In this paper, we prove the existence and multiplicity of subharmonic bouncing motions for a Hill's type sublinear oscillator with an obstacle. Furthermore, we also consider the existence, multiplicity and dense distribution of symmetric periodic bouncing solutions when the weight function is even. Based on an appropriate coordinate transformation …
