DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/137/"
 >Harmonic maps between singular spaces</a>\nby Yannick Sire (John Hopkins 
 Univ.) as part of CRM - Séminaire du CIRGET / Géométrie et Topologie\n\
 nLecture held in PK-5115.\n\nAbstract\nAfter reviewing briefly the classic
 al theory of harmonic maps between smooth manifolds\, I will describe some
  recent results related to harmonic maps with  free boundary\, emphasizin
 g on two different approaches based on recent developments by Da Lio and R
 iviere. This latter approach allows in particular to give another formulat
 ion which is well-suited for such maps between singular spaces. After the 
 works of Gromov\, Korevaar and Schoen\, harmonic maps between singular spa
 ces have been instrumental to investigate super-rigidity in geometry. I wi
 ll report on recent results where we introduce a new energy between singul
 ar spaces and prove a version of Takahashi’s theorem (related to minimal
  immersions by eigenfunctions) on RCD spaces.\n
