Popis: We consider cocycles over certain hyperbolic \({\mathbb{R}^k}\) actions, \({k\ge 2}\) , and show rigidity properties for cocycles with values in a Lie group or a diffeomorphism group, which are close to identity on a set of generators, and are sufficiently smooth. The actions we consider are Cartan actions of \({SL(n,\mathbb{R})/\Gamma}\) or \({SL(n,\mathbb{C})/\Gamma}\) , for \({n\ge 3}\) , and Γ torsion free cocompact lattice. The results in this paper rely on a technique developed recently by D. Damjanovic and A. Katok.
