iTHEMS Math Seminar by Prof. Siqi He on October 15, 2021

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.
