Introduction to Gauge theory
This course provides an introduction to Gauge theory in mathematics for graduate and advanced undergraduate students. We focus on Donaldson's theory on 4-manifolds, which involves the moduli space of anti-self-dual connections, and related gauge-theoretic invariants in four dimensions. The course begins with a review of connections and curvatures on vector bundles and principal G-bundles. Our aim is to understand the Uhlenbeck compactification of the moduli space, its role in formulating the Donaldson invariants, and the connection to the algebraic counterpart in the moduli problem of algebraic geometry. If time permits, we may discuss more advanced topics from the current research field.

讲师介绍
My research interests are primarily centred on Gauge theory within mathematics. Recently, my focus has been on semistable Higgs sheaves on complex projective surfaces and associated gauge-theoretic invariants, employing algebro-geometric methods. However, I also have a strong interest in working within the analytic category.
