Description:The annual Surveys in Differential Geometry volume is received with anticipation each year as it summarizes many of the recent discoveries in the field. This year's volume is dedicated to Professors Calabi, Lawson, Siu, and Uhlenbeck. It contains important contributions by their students and colleagues and reflects the important work in the field by these great mathematicians. The volume is suitable for graduate students and researchers interested in geometry and topology. Table of Contents: 1. Projective planes, Severi varieties and spheres - M. Atiyah and J. Berndt 2.
