Title:Fiber-bunched cocycles: cohomology and periodic data.
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Victoria Sadovskaya, Penn State
We consider Holder continuous fiber-bunched GL(d,R)-valued cocycles over a hyperbolic diffeomorphism. We show that if two cocycles have equal periodic data, then they are Holder continuously cohomologous. We obtain similar conclusions under weaker assumptions on the periodic data. We apply these results to the question when a hyperbolic toral automorphism is smoothly conjugate to a C^1-small perturbation.
