The goal of the conference was to bring together distinguished researchers from a variety of areas related to algebraic topology and its applications. The list of invited speakers included: Greg Arone, Sylvain Cappell, Jon Carlson, Fred Cohen, Jim Davis, Don Davis, Tom Goodwillie, Yakov Eliashberg, Tom Farrell, Mike Hopkins, Eleny Ionel, Ronnie Lee, Ib Madsen, Mark Mahowald, Bob Oliver, Peter Oszvath, John Rognes, Abigail Thompson, Ulrike Tillmann and Efim Zelmanov. A number of topics were covered in the lectures, including qomotopy theory, moduli spaces, group cohomology, manifold theory, algebraic K-theory, low dimen- sional topology, symplectic geometry, etc. Special emphasis was made on breadth and interactions between different areas. A large number of postdocs, graduate students and established mathematicians attended the lectures. This volume con- tains twelve refereed papers on a wide variety of topics reflecting the nature of the conference. The conference was partly held to celebrate Jim Milgram's sixtieth birthday and to recognize his enormous contributions to algebraic topology over the past 35 years. His powerful mathematics, deep insight and breadth of knowledge have been an inspiration to many of us, and it is a great pleasure for us to dedicate this volume to him. The first paper in this volume is an outline of Jim Milgram's main mathematical contributions.

Alejandro Adem Gunnar Carlsson Ralph Cohen vii Topology, Geometry, and Algebra: Interactions and New Directions Alejandro Adem, Gunnar Carlsson, and Ralph Cohen, Editors This volume presents the proceedings from the conference on "Topology, Geometry, and Algebra: Interactions and New Directions" held in honor of R. James Milgram at Stanford University in August 1999. The meeting brought together distinguished researchers from a variety of areas related to algebraic topology and its applications. Papers in the book present a wide range of subjects, reflecting the nature of the conference. Topics include moduli spaces, configuration spaces, surgery theory, homotopy theory, knot theory, group actions, and more. Particular emphasis was given to the breadth of interaction between the different areas. ISBN 0-8218-2063-X 9 780821 820636 CONM/279 .
