报告摘要：We prove that the Lyapunov exponents of integrable $\SL(2)$-cocycles over volume-preserving uniformly expanding mapsvary continuously with the cocycle in the $L^1$-topology except, precisely, when the cocycle is $L^1$-conjugate to a diagonal cocycle with non-zero exponents. This is a joint work with Jairo Bochi, Abel Rios Bravo and Marcelo Viana.
