内容説明・目次
内容説明
This book is a compendium of survey lectures presented at a conference on Riemannian Geometry sponsored by The Fields Institute for Research in Mathematical Sciences (Waterloo, Canada) in August 1993. Attended by over 80 participants, the aim of the conference was to promote research activity in Riemannian geometry. A select group of internationally established researchers in the field were invited to discuss and present current developments in a selection of contemporary topics in Riemannian geometry. This volume contains four of the five survey lectures presented at the conference. The book features basic notions of volume and entropy and the difficult and deep relations of these invariants to curvature. It also features $LP$ cohomology, in which the methods combine various areas of mathematics going beyond Riemannian geometry. It covers curvature inequalities from a general point of view, leading to the study of general spaces.
