| Jul 4, 2017 at 17:15 | comment | added | Ali Taghavi | @TerryTao You are well come. I think if we do not require $X$ to be unit vector, we can replace $\theta (X) =1$ by $\theta (X) >0$. BTW, I am interested in the concept of geodesible flow since many years ago. I mentioned it at this post: mathoverflow.net/questions/160945/… | |
| Jul 4, 2017 at 16:28 | comment | added | Terry Tao | Thanks for this! Looks like being geodesible is equivalent to the existence of a 1-form obeying the stronger conditions $\theta(X)=1$ and ${\mathcal L}_X(\theta) = 0$. The paper of Sullivan ams.org/mathscinet-getitem?mr=508734 referenced in Tondeur's book suggests that horocycle flows may be a source of counterexamples to the original question (will have to think about this...). | |
