Continuity of Lyapunov exponents for cocycles with invariant holonomies
(2018) [Journal article]We prove a conjecture of Viana which states that Lyapunov exponents vary continuously when restricted to GL(2,R)-valued cocycles over a subshift of finite type which admit invariant holonomies that depend continuously on ... -
Periodic approximation of exceptional lyapunov exponents for semi-invertible operator cocycles
(2019) [Journal article]We prove that for semi-invertible and Hölder continuous linear cocycles A acting on an arbitrary Banach space and defined over a base space that satisfies the Anosov closing property, all exceptional Lyapunov exponents of ... -
Removing zero Lyapunov exponents
(2003) [Journal article]In an explicit family of partially hyperbolic diffeomorphisms of the torus T 3, Shub andWilkinson recently succeeded in perturbing the Lyapunov exponents of the center direction. We present here a local version of their ...
