Invariant Reeb orbit conjecture for contactomorphisms

Let (Y,ξ)(Y,\xi) be a closed contact manifold equipped with a selected contact form α\alpha such that kerα=ξ\ker\alpha=\xi. Let ϕ\phi be a contactomorphism of YY that preserves α\alpha and is contact-isotopic to the identity. A ϕ\phi-invariant Reeb orbit is a Reeb trajectory whose image is shifted by ϕ\phi by some nonzero time. Invariant Reeb orbit conjecture. Every such ϕ\phi admits a ϕ\phi-invariant Reeb orbit. This is presented as a generalization of the Weinstein conjecture; the supplied text gives no resolution of the claim.
