Sandon's small oscillation conjecture for translated points

About 12 years old · traced to

Let (N,ξ)(N,\xi) be a contact manifold with a global contact form α\alpha, and let ψ\psi be a contactomorphism. Say that ψ\psi has small oscillation energy when its oscillation energy is sufficiently small, and call ψ\psi non-degenerate when its translated points are non-degenerate. Sandon's small oscillation conjecture. Every contactomorphism ψ\psi of small oscillation energy has at least one translated point, and if in addition ψ\psi is non-degenerate, then it must have at least

dim⁡H∗(N,Z/(2))\dim H_*(N,\mathbb{Z}/(2))

translated points. The result is proved under the additional hypothesis that (N,ξ)(N,\xi) admits a strong exact symplectic filling; removing that filling assumption is the proposed conjectural extension and remains open.
