A Gluing Theorem For Collapsing Warped-QAC Calabi-Yau Manifolds
Abstract
We carry out a gluing construction for collapsing warped-QAC (quasi-asymptotically-conical) Calabi-Yau manifolds in n+2, n≥ 2. This gluing theorem verifies a conjecture by Yang Li in li2019gluing on the behavior of the warped QAC Calabi-Yau metrics on affine quadrics when two singular fibers of a holomorphic fibration go apart. We will also discuss a bubble tree structure for those collapsing warped-QAC Calabi-Yau manifolds.
