DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/145/"
 >Algebro geometric aspects of bubbling of Kähler-Einstein metrics</a>\nby
  Cristiano Spotti (Aarhus University) as part of Geometria em Lisboa (IST)
 \n\n\nAbstract\nGiven a degenerating family of Kähler-Einstein metrics it
  is natural to study from a differential geometric perspective the collect
 ion of all metric limits at all possible scales\, a typical example being 
 the emergence of Kronheimer’s ALE spaces near the formation of orbifold 
 singularities for Einstein 4-manifolds. In this talk\, I will describe\, f
 ocusing on the discussion of some concrete and elementary examples\, how i
 t should be possible to use algebro geometric tools to investigate such pr
 oblem for algebraic families\, leading in the non-collapsing case to an in
 ductive argument identifying the so-called metric bubble tree at a singula
 rity (made of a collection of asymptotically conical Calabi-Yau varieties)
  with a subset of the non-Archimedean Berkovich analytification of the fam
 ily. Based on joint work with M. de Borbon.\n
