Marked lens rigidity conjecture for manifolds of Anosov type

About 4 years old · traced to

Let MM be a smooth manifold with boundary, and let g1g_1 and g2g_2 be smooth metrics of Anosov type on MM such that

g1∣T(∂M)=g2∣T(∂M).g_1|_{T(\partial M)}=g_2|_{T(\partial M)}.

Assume that g1g_1 and g2g_2 have the same marked lens data, meaning that their lens data agree and the corresponding geodesics are homotopic relative to their endpoints. Marked lens rigidity conjecture. There exists a smooth diffeomorphism ψ\psi, homotopic to the identity and equal to the identity on ∂M\partial M, such that

ψ∗g2=g1.\psi^*g_2=g_1.

This conjecture was solved in dimension 22 and locally for pairs of negatively curved metrics in higher dimensions; the general statement for manifolds of Anosov type is therefore recorded as solved according to the supplied status.
