RésumeIn this talk I will explain how to construct and classify all complete Calabi-Yau manifolds that are polynomially asymptotic to some given Calabi-Yau cone (with a smooth cross-section)at infinity. If the Reeb vector field of the cone generates a circle action, this result goes back to joint work with Ronan Conlon in 2014. In more recent joint work we were able to remove the assumption about the Reeb vector field. This now allows us to give a complete analysis of the most interesting class of examples - smoothings of cones over irregular Sasaki-Einstein manifolds - where only one sporadic example was known previously.
