Abstract:

In this talk for the polynomial vector fields of arbitrary degree in $mathbb{R}^3$ having the $2$--dimensional torus

$$mathbb{T}={(x,y,z) in mathbb{R}^3 : (x^2+y^2-a^2)^2+z^2=1},$$

with $a>1$, invariant by their flow we characterize all the possible configurations of invariant meridians and parallels that these vector fields can exhibit. Furthermore we analyze when these invariant either meridians or parallels can be limit cycles.

This is a joint work with Jaume Llibre.
