These obstructions are specific to the compact situation and raise the question of whether or not a sequence of Einstein metrics degenerating while bubbling out gravitational instantons has to be K\u00e4hler-Einstein. We then test these obstructions to discuss the possibility of producing a Ricci-flat but not K\u00e4hler metric by the promising desingularization configuration proposed by Page in 1981.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tristan Ozuch-Meersseman will talk on 10th November, at 1.45pm UK time, or 2.45pm Belgian time.
