Article:Ashwin, P., Rucklidge, A.M. and Sturman, R. (2004) Two-state intermittency near a symmetric interaction of saddle-node and Hopf bifurcations: a case study from dynamo theory. Physica D: Nonlinear Phenomena, We consider a irlodel of a Hopf bif~rcat~iorl intera~t~ing as a codiirlerlsiorl 2 bifurcation ~it~l.1 a saddle-node on a liirlit cycle, irl~t~ivat~ed by a low-order irlodel for magnet,ic act,ivit,y in a stellar dynamo. This irlodel corlsist,~ of coupled irlt,eract,iorls between a saddlenode arld t,wo Hopf bifurcat>ions, where the saddlenode bif~rcat~iorl is assuirled t,o liave global reirljectiorl of t,raject,ories. The irlodel car1 produce cl.laot,ic beliaviour wit,liin each of a pair of invariant subspaces, and also it can show at,t,ract,ors t>klat are stuck-on to b0t~l.1 of t,he inrrariant, subspaces. We imest,igat,e t,he det>ailed intjerinitjtjentj dyrlairlics for such an at,t,ract,or, irlriest,igat,irlg t,he effect of breaking t,he ~yirlirlet~ry bet>weerl t,he t,wo Hopf bifurcations, and observing t,l.lat it can appear via blowout, bif~rcat~iorls froirl t,he invariant subspaces.We give a siirlple llarkov chain irlodel for t,he t,west,at,e irlt,erinit,t,ent dyrlairlics t,l.iat, reproduces t,he t,iirle spent close t,o t,he invariant subspaces and t,he swit,cl.ling bet,weerl t,he different, possible i11variant~ subspaces: t>klis clarifies t,he obser~rat~ion t>klat t,he prop~rt~iorl of t>iirle spent, near the different subspaces depends on the average residence t>iirle and also on the pr~babilit~ies of ~wit~ching bet>weerl t,he possible subspaces. *P.Asl
