The Synthetic Geometry of the Weil-Petersson Metric
Jeffrey F. Brock (Brown University)
May 10 - 21, 2004
The last few years have seen many new results and broadening interest in the study of the Weil-Petersson metric on Teichmuller space and its metric completion. Improved estimates on the behavior of the metric near infinity have allowed for a deeper understanding of the behavior of geodesics than was previously available.
In this mini-course, Dr. Brock gave an overview of the central background results and estimates needed, described recent developments in the large-scale and synthetic geometry of the Weil-Petersson metric, and described an emerging conjectural picture of the behavior of geodesics. Topics included:
Classical Problems in Commutative Algebra
June 7 - 18, 2004
The Department of Mathematics at the University of Utah hosted a two week mini-course on homological conjectures in commutative algebra. During the past 30 years, the homological conjectures and related questions have had a significant impact on the development of commutative algebra. These problems originated in the work of Serre, Auslander, Peskine, Szpiro, and others. In 1974, Mel Hochster gave an overview of these problems in a series of lectures providing answers to some of the questions and indicating further directions of research. Since then, important contributions were made by various experts and some of these conjectures have been solved. However, some of them still await answers. This area of research remains a rich one and is as influential today in the development of commutative algebra as it was decades ago.
The aim of the mini-course was to introduce graduate students with some background in commutative algebra and young researchers to this area of research. The lectures provided an introduction to the subject, an overview of the main contributions of the past decades, as well as a discussion of the remaining open questions. The first week developed the fundamental concepts needed in the second week when the major directions of research were discussed.
