Course description and aims

We explain basic materials in the theory of complex manifolds. We introduce basic examples of complex manifolds, and then introduce the concept of harmonic differential forms. These establish basic results in geometry. For complex manifolds, the concept of Dolbeault groups naturally makes sense, and we can represent their elements by harmonic forms. If the manifolds are moreover Kaehler, harmonic forms as a real manifold and a complex manifold agree, and it induces a constraint on the topology of such manifolds.

Student learning outcomes

・to be familiar with basic examples of complex manifolds and basic concept such as first Chern class and blow-up,
・to understand cohomology and harmonic forms
・to know (Hodge) decomposition of differential forms on a closed real manifold and compact complex manifolds
