The simplest, and very common symmetry of this type is the equivariance of the defining equations under the orthogonal group O(2). We formulate a novel symmetry reduction scheme for such systems by combining the method of slices with invariant polynomial methods, and show how it works by applying it to the Kuramoto–Sivashinsky system in one spatial dimension. As an example, we track a relative periodic orbit through a sequence of bifurcations to the onset of chaos. Within the symmetry-reduced state space we are able to compute and visualize the unstable manifolds of relative periodic orbits, their torus bifurcations, a transition to chaos via torus breakdown, and heteroclinic connections between various relative periodic orbits. It would be very hard to carry through such analysis in the full state space, without a symmetry reduction such as the one we present here.","lang":"eng"}],"date_created":"2018-12-11T11:50:44Z","date_published":"2017-05-01T00:00:00Z","scopus_import":1,"date_updated":"2021-01-12T06:49:07Z","type":"journal_article","oa":1,"_id":"1211","citation":{"mla":"Budanur, Nazmi B., and Predrag Cvitanović. “Unstable Manifolds of Relative Periodic Orbits in the Symmetry Reduced State Space of the Kuramoto–Sivashinsky System.” <i>Journal of Statistical Physics</i>, vol. 167, no. 3–4, Springer, 2017, pp. 636–55, doi:<a href=\"https://doi.org/10.1007/s10955-016-1672-z\">10.1007/s10955-016-1672-z</a>.","short":"N.B.
