SUMMARY: (...): Invited speaker: Alexander BUFETOV at Pisa
DESCRIPTION:: The conference will focus on renormalization schemes\, which 
 often enable to understand the dynamics of a parabolic or elliptic system 
 in a given family through the study of an auxiliary hyperbolic system. Wel
 l-known examples of renormalization include the classical Gauss map\, whic
 h renormalizes rotations of the circle\, the geodesic flow on a surface of
  constant negative curvature\, which renormalizes the corresponding horocy
 cle flow\, and more generally the Teichmueller flow and the Rauzy-Veech in
 duction\, which provide an effective renormalization scheme for interval e
 xchange transformations.\n\nThe core will be the interplay between dynamic
 al systems and arithmetic\, and in particular the study of discrete arithm
 etic algorithms of significance in dynamics and geometry.\nWe will discuss
  in particular recent developments in the ergodic theory of continued frac
 tions and their various one and multidimensional generalizations.\n\nSigni
 ficant importance will be given to fractals arising naturally as geometric
  pictures of numeration systems and their topological properties\, as well
  as to the application of renormalization techniques in symbolic dynamics.
