Verhulst %J Mathematics %D 2009 %I arXiv %X We use an averaging approach to prove bifurcation of asymptotically stable periodic solutions in a bi-linear oscillator whose one spring has nearly infinite stiffness. This leads to a singularly perturbed problem where the classical theory does not apply. %U http://arxiv.org/abs/0909.4354v1
