Learning objectives

Learn basic notions on complex algebraic manifolds. Understanding which complex manifold is isomorphic to an algebraic subvariety of some complex projective space.

Prerequisites

Holomorphic functions of one complex variable. Complex manifolds. Hodge theory on Kaehler manifolds.

Course unit content

Holomorphic functions of several variables. Sheaf theory and sheaf cohomology. Holomorphic vector bundles and divisors. Blow-ups. Hermitian vector bundle, connections, curvature and Chern classes. Applications of cohomology.

Full programme

Holomorphic functions of several variables (Hartogs' Teorem, Weierstrass' Theorems, Riemann' extension Theorem, Nullstellensatz). Sheaf theory and sheaf cohomology (rudiments of homological algebra, abstract de Rham Theorem, de Rham and Dolbeault Theorems). Holomorphic vector bundles (canonical bundle, adjunction formula, Kodaira dimension) and divisors (relations with line bundles, Kobaira map, divisors on curves). Blow-ups (canonical bundle of a blow-up). Hermitian vector bundle, connections, curvature and Chern classes (Serre duality, Bianchi identity, Chern connection, positive vector bundles). Applications of cohomology (Kodaira vanishing Theorem, Kodaira embedding Theorem, Riemann-Roch theorem on curves and Hirzebruch-Riemann-Roch formula).
