Hodge theory reading seminar

The goal of the seminar is to study the basics of Hodge theory, including the Hodge and Lefschetz decompositions on the cohomology of a Kähler manifold. We will follow Claire Voisin's Hodge Theory and Complex Algebraic Geometry I (Amazon).

If time permits, we can study Serre's GAGA paper, which has quite a different flavour, to relate the results obtained in complex geometry to the algebraic world. The article is available online.

The book has a small but useful selection of exercises (typically between 1 and 4 per chapter), and I encourage everyone to look at them as well. I will distribute them weekly to those interested.

Organisers: Remy van Dobben de Bruyn, Sébastien Picard.

Time and location: Monday 16:30-18:00 in Math 622.
