Periodic data rigidity of Anosov automorphisms with Jordan blocks
arXiv:2210.16702 · doi:10.1017/etds.2024.56
Abstract
Anosov automorphisms with Jordan blocks are not periodic data rigid. We introduce a refinement of the periodic data and show that this refined periodic data characterizes conjugacy for Anosov automorphisms of the four dimensional torus with a Jordan block.
