In this article we study the center problem for polynomial BiLiénard
systems of degree n. Computing the focal values and using Gröbner bases we
end the center conditions for such systems for n = 6. We also establish a
conjecture about the center conditions for polynomial BiLiénard systems of
arbitrary degree.

Center problem for trigonometric Liénard systems
Gasull, Armengol; Giné, Jaume; Valls, Claudia (Elsevier, 2017)We give a complete algebraic characterization of the non-degenerated centers for planar trigonometric Liénard systems. The main tools used in our proof are the classical results of Cherkas on planar analytic Liénard systems ...
