DESCRIPTION:Jérôme Bolte\nThe study of the behavior of seqeunces generat
 ed by Sequential Quadratic Programming (SQP) or Sequential Convex Programm
 ing method (SCP) is a difficult matter: sequences can oscillate\, active c
 onstraints seem to have an unpredictable behaviour\, cluster points are mo
 st of the time KKT points but oscillations can still occur\, value converg
 ence can be arbitratril slow.. All these counter-intuitive phenomena can o
 ccur with indefinitely smooth data and nice qualifcation conditions\, yet 
 they do not occur in real life perhaps because of some numerical obstructi
 on.\nHow can we explain this discrepancy between theory and practice? The 
 object of this talk is to show that semi-algebraicity (subanalyticity / de
 finability) gives an elegant answer to this apparent contradiction.\nJoint
  work with E.Pauwels (Toulouse\, France).
