DESCRIPTION:Title: Sign-changing blowing-up solutions to the Yamabe equatio
 n on a closed Riemannian manifold\n\nAbstract: In this talk\, I will discu
 ss the question of existence of families of sign-changing solutions to the
  Yamabe equation\, which blow up in the sense that their maximum values te
 nd to infinity. It is known that in the case of positive solutions\, there
  does not exist any blowing-up families of solutions to this problem in di
 mensions less than 25\, except in the case of manifolds conformally equiva
 lent to the round sphere (Khuri\, Marques and Schoen\, 2009). I will prese
 nt a construction showing the existence of a non-round metric on spherical
  space forms of dimensions greater than 10 for which there exist families 
 of sign-changing blowing-up solutions to this problem. Moreover\, the solu
 tions we construct have the lowest possible limit energy level. As a count
 erpart\, we will see that such solutions do not exist at this energy level
  in dimensions less than 10. This is a joint work with Bruno Premoselli (U
 niversité Libre de Bruxelles).\n\nZoom link: https://umontreal.zoom.us/j/8
