DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BOWL/4/">Hig
 her order obstructions to the desingularization of Einstein metrics</a>\nb
 y Tristan Ozuch-Meersseman (MIT) as part of B.O.W.L Geometry Seminar\n\n\n
 Abstract\nWe exhibit new obstructions to the desingularization of Einstein
  metrics in dimension 4. These obstructions are specific to the compact si
 tuation and raise the question of whether or not a sequence of Einstein me
 trics degenerating while bubbling out gravitational instantons has to be K
 ähler-Einstein. We then test these obstructions to discuss the possibilit
 y of producing a Ricci-flat but not Kähler metric by the promising desing
 ularization configuration proposed by Page in 1981.\n
