本书对超越代数几何领域的一个核心课题 ——Hodge猜想进行了介绍。本书适合对超越方法和Hodge理论以及Calabi-Yau流形、镜像对称或量子上同调感兴趣的研究生以及数学研究人员阅读参考。This book provides an introduction to a topic of central interest in transcendental algebraic geometry: the Hodge conjecture. Consisting of 15 lectures plus addenda and appendices, the volume is based on a series of lectures delivered by Professor Lewis at the Centre de Recherches Mathématiques (CRM).The book is a self-contained presentation, completely devoted to the Hodge conjecture and related topics. It includes many examples, and most results are completely proven or sketched. The motivation behind many of the results and background material is provided. This comprehensive approach to the book gives it a “user-friendly” style. Readers need not search elsewhere for various results. The book is suitable for use as a text for a topics course in algebraic geometry; includes an appendix by B. Brent Gordon.
