%0 Journal Article %T Dissipative homoclinic loops and rank one chaos %A Qiudong Wang %A William Ott %J Mathematics %D 2008 %I arXiv %X We prove that when subjected to periodic forcing of the form $p_{\mu, \rh, \om} (t) = \mu (\rh h(x,y) + \sin (\om t))$, certain second order systems of differential equations with dissipative homoclinic loops admit strange attractors with SRB measures for a set of forcing parameters $(\mu, \rh, \om)$ of positive measure. Our proof applies the recent theory of rank one maps, developed by Wang and Young based on the analysis of strongly dissipative H\'enon maps by Benedicks and Carleson. %U http://arxiv.org/abs/0802.4283v2
