| Abstract: |
|---|
| 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. |
