Complex Geometry: An Introduction
Author: Daniel Huybrechts
Publication: 2005 (first paperback publication listed in late 2004)
Publisher: Springer Berlin Heidelberg
Daniel Huybrechts’ Complex Geometry: An Introduction is a graduate-level introduction to the geometry of complex manifolds, a subject lying at the intersection of complex analysis, differential geometry, and algebraic geometry. Rather than treating these areas separately, Huybrechts develops the machinery needed to understand how analytic, topological, and geometric structures interact on complex manifolds. The book begins with the local theory—holomorphic functions of several variables, complex and Hermitian structures, and differential forms—before moving to complex manifolds themselves, including holomorphic vector bundles, divisors, line bundles, projective space, and blow-ups.
A central part of the book is devoted to Kähler geometry, where complex, symplectic, and Riemannian ideas come together. Huybrechts develops Kähler identities, Hodge theory, and Lefschetz theorems before giving a substantial treatment of vector bundles, connections, curvature, and Chern classes. These tools lead naturally to major results such as the Hirzebruch–Riemann–Roch theorem, Kodaira vanishing theorem, and Kodaira embedding theorem. The final chapter introduces deformations of complex structures through the Maurer–Cartan equation and related machinery. Appendices extend the discussion toward Hodge structures, Kähler–Einstein metrics, holonomy, supersymmetry, and deformation theory, connecting the classical foundations with topics important in Calabi–Yau geometry and mirror symmetry.
Although advertised as accessible, this is not an elementary geometry book. It is best suited to advanced undergraduate or beginning graduate students already comfortable with complex analysis, linear algebra, topology, and some differential geometry. One of its strengths is that Huybrechts assumes comparatively little prior knowledge of differentiable manifolds and functional analysis while still reaching sophisticated modern mathematics. Numerous exercises are integrated into the development, making the book suitable both for a two-semester course and for serious self-study. Its greatest value is perhaps as a bridge: it takes a reader from classical complex analysis and manifold theory to the language used in modern algebraic geometry, Hodge theory, and mathematical physics.

Key takeaways
- Complex geometry unifies several fields: the book demonstrates how complex analysis, differential geometry, topology, and algebraic geometry interact through complex manifolds.
- Kähler geometry is the centerpiece: Hodge theory, Kähler identities, Lefschetz theory, curvature, and characteristic classes provide much of the book's conceptual backbone.
- It progresses toward major modern results: Hirzebruch–Riemann–Roch, Kodaira vanishing and embedding, deformation theory, and Kähler–Einstein geometry appear naturally after the foundations have been established.
- Excellent preparation for advanced topics: particularly useful for readers intending to study Calabi–Yau manifolds, mirror symmetry, Hodge theory, algebraic geometry, or mathematical aspects of string theory.
