Hodge theory and period maps (Spring 2026)

 

What is this course about?

This course introduces Hodge theory and period maps, which lie at the intersection of complex geometry, algebraic geometry, and arithmetic. Starting from the Hodge decomposition of the cohomology of smooth complex algebraic varieties, we develop variations of Hodge structure and their basic properties. We then study period domains and period maps, which encode how Hodge structures vary in families, and explore their geometric and arithmetic significance.​

 

Prerequisite

Basic knowledge of complex manifolds.
