July 17, 2015. A pinching and twisting monoid of symplectic matrices which is not Zariski dense in the full symplectic group. Consider a random product of two symplectic matrices. On a real symplectic vector space. That is, the (symplectic). Is the shift map equipped with the Bernoulli measure. By Oseledets multiplicative ergodic theorem. The Lyapunov exponents of the random product of. Ie, the linear cocycle. Describing the exponential growth of the singular values of the random products. Of course, the...

May 4, 2009. Sur le cocycle de Kontsevich-Zorich au-dessus de deux origamis spéciaux (slides of a talk in Orsay). Firstly, let me apologize for the 1 month and half hiatus: while I plan to close up my series on the talks and courses of the Dynamical Systems conference (held at ICTP, Italy), I wasn’t able to do so during April because I was learning some interesting facts about square-tiled surfaces and Teichmuller dynamics from my new friends Pascal Hubert. Invariant ergodic probability is. Ie, all expon...

June 30, 2015. Hausdorff dimension of the graphs of the classical Weierstrass functions (after Weixiao Shen). About two weeks ago, Weixiao Shen gave the talk “. Hausdorff dimension of the graphs of the classical Weierstrass functions. 8221; during the Third Palis-Balzan International Symposium on Dynamical Systems. In the sequel, I will transcript my notes from Shen’s talk. In Real Analysis, the classical Weierstrass function. Note that the Weierstrass functions have the form. Weierstrass (1872) and Hardy.
