Recent developments in topology and analysis have led to the creation of new
lines of investigation in differential geometry. The 2000 Barrett Lectures
present the background, context and main techniques of three such lines by
means of surveys by leading researchers.

The first chapter (by Alice Chang and Paul Yang) introduces new classes of
conformal geometric invariants, and then applies powerful techniques in
nonlinear differential equations to derive results on compactifications of
manifolds and on Yamabe-type variational problems for these invariants. This is
followed by Karsten Grove's lectures, which focus on the use of isometric group
actions and metric geometry techniques to understand new examples and
classification results in Riemannian geometry, especially in connection with
positive curvature. The chapter written by Jon Wolfson introduces the emerging
field of Lagrangian variational problems, which blends in novel ways the
structures of symplectic geometry and the techniques of the modern calculus of
variations.

The lectures provide an up-do-date overview and an introduction to
the research literature in each of their areas. This very readable
introduction should prove useful to graduate students and researchers
in differential geometry and geometric analysis.
