Abstract
In this talk I will construct more complete Calabi-Yau metrics of Calabi type. They are higher-dimensional analogues of ALH* gravitational instantons in two dimensions. This work builds on and generalizes the results of Tian-Yau and Hein-Sun-Viaclovsky-Zhang, creating Calabi-Yau metrics that are only polynomially close to the model space. I will also show the uniqueness of such metrics in a given cohomology class with fixed asymptotic behavior.
