Center conditions and limit cycles for BiLiénard systems
MetadataShow full metadata
In this article we study the center problem for polynomial BiLiénard systems of degree n. Computing the focal values and using Gröbner bases we find 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.
