Periodic solutions of polynomial non-autonomous differential equations. <i>Electronic Journal of Differential Equations, 2005</i>(84), pp. 1-8.1072-6691https://hdl.handle.net/10877/13685We present some results on the number of periodic solutions for scalar non-autonomous polynomial equations of degree five. We also consider a class of polynomial equations of any degree. Our results give upper bounds for the number of limit cycles of two-dimensional systems.Text8 pages1 file (.pdf)enAttribution 4.0 InternationalPeriodic solutionsPolynomial non-autonomous equationsAbel differential equationsLimit cyclesUniformly isochronous centersHilbert's sixteenth problemPeriodic solutions of polynomial non-autonomous differential equationsArticleThis work is licensed under a Creative Commons Attribution 4.0 International License.
