DESCRIPTION:Prof. Stéphane Jaffard\, Université Paris-Est Créteil\nMult
 ifractal analysis was introduced by physicists with the purpose of using g
 lobal regularity indices in order to study the intimate structure of fully
  developed turbulence. A later motivation was to explain the results obser
 ved as the signature of the presence of pointwise singularities of differe
 nt "strengths'" in the data.\nThe heuristic arguments relating global and 
 pointwise regularity which were introduced for that purpose proved extreme
 ly powerful inside mathematics\, supplying unifying concepts with a surpri
 singly wide range of applications: Large classes of functions arising in h
 armonic analysis\, or stochastic processes have been revisited using this 
 approach\, and were shown to display fractal sets of singularities of vary
 ing fractal dimensions.\nBio: Since September 1995: Professor at UPEC Univ
