Log-Höder continuity at zero Lyapunov gap for finite state Markov -cocycles
El Hadji Yaya Tall
We prove that the extremal Lyapunov exponents of finite-state Markov -cocycles are pointwise log-Hölder continuous, jointly in the cocycle matrices and t…

Analyticity of Lyapunov Exponents for Mixed Markov Quasi-Periodic Cocycles
EL Hadji Yaya Tall
We study the dependence of the top Lyapunov exponent of a mixed Markov quasi-periodic cocycle on the transition probabilities. The transition matrix is assumed primitive, the Marko…

Analyticity of the Lyapunov exponents of random products of quasi-periodic cocycles
Jamerson Bezerra, Adriana Sánchez, El Hadji Yaya Tall
We show that the top Lyapunov exponent , with for each , associated with a random product of quasi-periodic cocycles depends real anal…
