DESCRIPTION:Title:Compactness of sign-changing solutions to critical ellipt
 ic equations with bounded negative part\n	Abstract: In this talk\, we will 
 look at the question of compactness of sign-changing solutions to a class 
 of critical elliptic Schrödinger equations on a closed Riemannian manifold
 . We will present a sharp compactness result for the set of sign-changing 
 solutions with bounded negative part. We obtained this result in dimension
 s greater than or equal to 7 when the potential function is below the geom
 etric threshold of the conformal Laplacian. The whole set of sign-changing
  solutions is non-compact in general. We will also discuss constructions o
 f counterexamples in the case of the sphere in dimensions less than or equ
 al to 6 and for potentials above the geometric threshold in higher dimensi
 ons. This is a joint work with Bruno Premoselli (ULB\, Bruxelles).\n\n \n
