vector field with no periodic orbits that are non constants












0












$begingroup$


Give an example of non periodic vector field X on $mathbb{R}^2 $ non identically zero with a compact support such that X has no periodic orbits that are non constants.



I am not sure how I should interpret this question. If X has periodic orbits, they should be constant. But then the period is T=0 so they are non periodic? is it a contradiction?



Thank you for any insights.
