Smooth rigidity for codimension one Anosov flows
Andrey Gogolev, Federico Rodriguez Hertz
We introduce the matching functions technique in the setting of Anosov flows. Then we observe that simple periodic cycle functionals (also known as temporal distance functions) pro…

Smooth rigidity for very non-algebraic Anosov diffeomorphisms of codimension one
Andrey Gogolev, Federico Rodriguez Hertz
In this paper we introduce a new methodology for smooth rigidity of Anosov diffeomorphisms based on "matching functions." The main observation is that under certain bunching assump…
