Differential Geometry SeminarOrganizers:Jialong Deng, Akito FutakiSpeaker:Yifan Chen (Berkeley)Time:Tues., 21:00-22:00, Dec. 3, 2024Title:More Complete Calabi-Yau Metrics of Calabi TypeAbstract:We construct more complete Calabi-Yau metrics asymptotic to Calabi ansatz. They are the higher-dimensional analogues of two dimensional ALH* gravitational instantons. Our work builds on and generali...
AbstractI will start by reviewing an old joint work with Davesh Maulik and Yukinobu Toda on relating Gromov-Witten, Gopakumar-Vafa and stable pair invariants on compact Calabi-Yau 4-folds. For non-compact CY4 like local curves, similar invariants can be studied via the perspective of quasimaps to quivers with potentials. In a joint work in progress with Gufang Zhao, we define a virtual count fo...
