Course description and aims

Overviewing basic notions in differential geometry and complex geometry, some advanced topics such as relevance of Ricci curvature with the topology of manifolds will be treated. Basic properties of K3 surfaces might be also included.

Student learning outcomes

・To understand special properties of compact Kaehler manifolds.
・To understand basic properties of "positive" line bundle over complex manifolds
・To understand basic properties of compact Kaehler surfaces
・To understand "special" Riemannian manifolds such as Kaehler manifolds and Ricci flat Kaehler manifolds, in terms of holonomy group
・To understand Calabi conjecture and its consequences

Keywords

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
