DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/185/"
 >Degenerations of exotic Calabi-Yau metrics through Atiyah's flop</a>\nby 
 Thibault Langlais (Humboldt-Universität zu Berlin) as part of Geometria e
 m Lisboa (IST)\n\n\nAbstract\nThe goal of this talk is to present the cons
 truction of new families of complete Calabi-Yau metrics with maximal volum
 e growth on the small resolutions of the ordinary double point singularity
  in dimension 3. These metrics have tangent cone $\\mathbb{C} ×(\\mathbb{
 C}^2/\\mathbb{Z}_2)$ at infinity and are parametrised by their Kähler cla
 ss. As the Kähler class degenerates\, the metrics converge in the pointed
  Gromov-Hausdorff sense to a singular Calabi-Yau metric with an isolated c
 onical singularity modelled on the Stenzel metric at the ordinary double p
 oint\, thereby providing a new metric realisation of the Atiyah flop. As w
 e will explain\, this construction is meant to provide a local adiabatic m
 odel for certain degenerations of compact Calabi-Yau manifolds.\n
