On the structural instability of non-hyperbolic limit cycles on planar polynomial vector fields

P Santana - São Paulo Journal of Mathematical Sciences, 2024 - Springer
It is known that non-hyperbolic limit cycles are structurally unstable in the set of planar
smooth and analytic vector fields. In the polynomial case, it is known only that limit cycles of …
