2021-11-24 Seminar Report

In this seminar, Professor Siqi He started with mean curvatures and minimal submanifolds in differential geometry. Then he introduced the notion of calibrated geometry of Harvey-Lawson. As important examples of calibrated submanifolds, special Lagrangian submanifolds in Calabi-Yau manifolds are introduced. Then he explained a branch cover problem raised by Simon Donaldson and sketched a proof of it.
