I will explain how a technique controlling the continuity of Lyapunov exponents allows to prove this conjecture in the case of smooth surface diffeomorphisms. This is a joint work with Jérôme Buzzi and Omri Sarig.</p></div> <hr> <p style="font-size: 1em"><b>Viernes 17/2 a las 14:30</b><br><b>Salón de seminarios del IMERL</b></p> <p style="font-size: 1em"><b>Contacto: </b>Santiago Martinchich - <a rel="external nofollow noopener noreferrer" target="_blank" tabindex="-1" href="mailto:smartinchich@cmat.edu.uy">smartinchich@cmat.edu.uy</a></p> <hr> <p>Vuelve el seminario de dinámica!</p> <p>Próxima semana: Maik Gröger (Jagiellonian University)</p> <hr>Más seminarios en: <a rel="external nofollow noopener noreferrer" target="_blank" tabindex="-1" href="http://www.cmat.edu.uy/seminarios">http://www.cmat.edu.uy/seminarios</a> </div></div></div></blockquote> <signature></signature> </div></div></div></div></body></html>
