DESCRIPTION:Speaker: Sylvain Crovisier\nhosted by Kaloshin Group\nAbstract:
  I will explain a relation between the discontinuities of the Lyapunov exp
 onents and of the entropy\, with respect to the invariant measures of smoo
 th diffeomorphisms of surfaces.Among the consequences\, one gets an answer
  to a conjecture by Viana on surfaces: if the Lyapunov exponents are posit
 ive for a set with positive area\, there exists an SRB measure.This is a j
 oint work with J. Buzzi and O. Sarig.
