Seminário de Sistemas Dinâmicos 7 de Outubro 2009, 14h30 Expoentes de Lyapunov para cociclos com valores em $SL(2,R)$ Abstract: Sketch of an alternative proof of a formula of Herman, Avila and Bochi for the Lyapunov exponents of linear cocycles valued in SL(2,R). The proof is based on certain symmetries of the action of the group SL(2,R) on the projective line, and does not use M. Herman' subharmonicity trick. | back |
