DESCRIPTION:Title: Existence of infinitely many solutions for the Einstein-
 Lichnerowicz system\n	Abstract: We will consider in this talk the Einstein-
 Lichnerowicz system of equations. It originates in General Relativity as a
  way to determine initial-data sets for the evolution problem. This system
  takes the form of a strongly coupled\, supercritical\, nonlinear system o
 f elliptic PDEs. We will investigate its blow-up properties and show that\
 , under some assumptions on the physics data\, it possesses a non-compact 
 family of solutions. This family of solutions will be constructed by combi
 ning toplogical methods with a finite-dimensional reduction approach\; due
  to the non-variational structure of the system\, the latter has to be car
 ried on in strong spaces and relies of a priori blow-up estimates that we 
 shall describe.\n
