A finite Livshits theorem and local length spectrum rigidity

Jonathan DeWitt, Spencer Durham, James Marshall Reber +1

We show that for closed negatively curved Riemannian manifolds whose length spectrum is exponentially separated, the length spectrum is a local isometry invariant. In particular, t…

Effective Equidistribution for Contact Anosov flows in Dimension Three

Asaf Katz, Thomas Aloysius O'Hare

We prove effective equidistribution theorems for (weighted) packets of closed periodic orbits for Anosov flows. In particular, for the case of contact Anosov flows on three-dimensi…

Finite Periodic Data Rigidity For Two-Dimensional Area-Preserving Anosov Diffeomorphisms

Thomas Aloysius O'Hare

Let $f, g$ be $C^{2}$ area-preserving Anosov diffeomorphisms on $T^{2}$ which are topologically conjugate by a homeomorphism $h$ ( $h f = g h$ ). We assume that the Jacobian periodic…

Finite Data Rigidity for One-Dimensional Expanding Maps

Thomas O'Hare

Let $f, g$ be $C^{2}$ expanding maps on the circle which are topologically conjugate. We assume that the derivatives of $f$ and $g$ at corresponding periodic points coincide for some…
