A generic bounded linear cocycle has simple Lyapunov spectrum

Abstract

We show that the set of cocycles with integral separateness is open and dense in the space of all bounded $Gl(d,{\mathbb R})$-cocycles equipped with uniform topology. As a consequence, a generic bounded linear cocycle has simple Lyapunov spectrum and dominated Oseledets splitting, and a generic bounded $Sl(2,\mathbb R)$-cocycle is uniformly hyperbolic.
