From the results of the linear stability analysis of symmetric periodic orbits, it is shown how, via gluing bifurcations, some quasi-periodic flows recover, as sets, symmetries lost in previous bifurcations. It is also shown how the same mechanism gives rise to a temporal chaotic attractor consisting of random switches between the symmetry-conjugate quasi-periodic orbits. At higher Rayleigh numbers, a chaotic-drifting behavior is found when a circle of invariant tori loses stability. In addition, detailed information about the Floquet multipliers and eigenfunctions of the periodic orbits involved in this dynamics is supplied.<\/jats:p>","DOI":"10.1142\/s0218127405014404","type":"journal-article","created":{"date-parts":[[2006,3,3]],"date-time":"2006-03-03T11:45:38Z","timestamp":1141386338000},"page":"3953-3972","source":"Crossref","is-referenced-by-count":5,"title":["SYMMETRIC PERIODIC ORBITS AND GLOBAL DYNAMICS OF TORI IN AN O(2) EQUIVARIANT SYSTEM: TWO-DIMENSIONAL THERMAL CONVECTION"],"prefix":"10.1142","volume":"15","author":[{"given":"MARTA","family":"NET","sequence":"first","affiliation":[{"name":"Departament de F\u00edsica Aplicada, Universitat Polit\u00e8cnica de Catalunya, M\u00f2dul B4.
