Existence of quasi-periodic invariant tori for coupled van der Pol equations. <i>Electronic Journal of Differential Equations, 2019</i>(88), pp. 1-22.1072-6691https://hdl.handle.net/10877/14976This work focuses on the existence of quasi-periodic invariant tori for coupled van der Pol equations. Using averaging method, a series of reversible transformations and KAM techniques, we prove that there exist quasi-periodic invariant tori for most parameters. The results in this article can be regarded as a generalization of those in [22].Text22 pages1 file (.pdf)enAttribution 4.0 InternationalCoupled van der Pol equationsKAM theoryInvariant torusArticle
