Introduction to Hodge theory
In a nutshell, Hodge theory is the study of cohomology groups of complex manifolds using harmonic differential forms. With its
many extensions and ramifications, it has become a very important tool in algebraic/complex geometry, and has interrelations with
other subjects such as number theory and string theory.
The goal of this course is to give a first introduction to Hodge theory. The first half of this lecture will be devoted to presenting some basic foundational results of the theory, such as the Hodge decomposition and the hard Lefschetz theorem, which are very important in algebraic geometry. In the second half, several further topics will be discussed. Possible topics include: (mixed) Hodge structures; Hodge theory and algebraic cycles; families of Hodge structures and period maps
Prerequisites: Knowledge of differentiable manifolds and complex analysis in one variable will be assumed. Some knowledge of algebraic geometry will be helpful especially in the second half of the lecture but is not a strict requirement.
Broadening: For those Oxford students who would like to do a broadening: please do get in touch with Tiago and myself via email.
