Sin.-English Ser. 31, 1113–1122 (2015)http://hdl.handle.net/10400.2/13898Let AC_D(M,SL(d,R)) denote the pairs (f,A) so that f ∈ A ⊂ Diff (M) is a C^1-Anosov transitive diffeomorphisms and A is an SL(d,R) cocycle dominated with respect to f. We prove that open and densely in AC_D(M,SL(d,R)), in appropriate topologies, the pair (f,A) has simple spectrum with respect to the unique maximal entropy measure μ_f. Then, we prove prevalence of trivial spectrum near the dynamical cocycle of an area-preserving map and also for generic cocycles in Aut_Leb(M) × Lp(M,SL(d,R)).engLinear cocyclesLyapunov exponentsAnosov diffeomorphismsTopological conjugacyMaximal entropy measuresjournal article10.1007/s10114-015-4417-z
