Four-Dimensional Manifolds and Projective Structure

這本書可以被視為對微分幾何的介紹，特別是對於四維流形的介紹，同時也是對流形中專案結構和專案相關性研究的介紹。

Graham Hall, FRSE is Professor Emeritus in the Institute of Mathematics at the University of Aberdeen, Scotland, UK. He received his PhD from the University of Newcastle upon Tyne in 1971 and came to Aberdeen in 1973. He also served as the Head of department at the University of Aberdeen from 1992 - 1995. His interests lie in classical mathematical relativity theory and differential geometry. He is the author of the text Symmetries and Curvature Structure in General Relativity (World Scientific, 2004) and has contributed to, or edited, several other texts. He has also delivered over 200 invited talks on these topics at many universities and academies in Europe, North and South America, Asia, Africa and Australasia and has published over 180 papers in scientific research journals.
Dr Hall is a Fellow of the Royal Society of Edinburgh and of the Royal Astronomical Society and serves on the editorial board of many scientific research journals worldwide.
