Title: Uniqueness in the local Donaldson-Scaduto conjecture
Speaker: Gorapada Bera, Simons Center for Geometry and Physics
Location: Math P-131
Abstract:
The local Donaldson-Scaduto conjecture predicts the existence and uniqueness of a special Lagrangian pair of pants in the Calabi-Yau 3-fold which is a product of an ALE hyperkahler 4-manifold of A2 type and the complex plane. The existence of this special Lagrangian has previously been proved by Esfahani and Li. This talk focuses on proving uniqueness, showing that no other special Lagrangian pair of pants satisfies this conjecture. This talk is based on arXiv:2412.19219 joint work with Esfahani and Li.
