The launch of this Advanced Lectures in Mathematics series is aimed at keeping mathematicians informed of the latest developments in mathematics， as well as toaid in the learning of new mathematical topics by students all over the world. Each volume consists of either an expository monograph or a collection of signify cant introductions to important topics， This series emphasizes the history and sources of motivation for the topics under discussion， and also gives an overview of the current status of research in each particular field. These volumes are the first source to which people will turn in order to learn new subjects and to dis cover the latest results of many cutting-edge fields in mathematics.
This book contains many substantial papers from distinguished speakers of a conference ”Geometric Analysis： Present and Future" and an overview of the works of Professor Shing-Tung Yau. Contributors include E. Witten， Y.T. Siu， R. Hamilton， H. Hitchin， B. Lawson， A. Strominger， C. Vafa， W. Schmid， V. Guillemin， N. Mok， D. Christodoulou. This is a valuable reference that gives an up-to-dated summary of geometric analysis and its applications in many different areas of mathematics.
