This volume contains papers on a wide range of topics in lowdimensional
topology. It arose out of two events that were held in 2003. The first was
the 28th University of Arkansas Spring Lecture Series in the Mathematical
Sciences, which took place April 1012, 2003. These annual conferences
focus on a specific topic of current interest in mathematics, and feature
a principal lecturer who gives a series of five lectures and selects
additional invited speakers. In 2003 the principal lecturer was Andrew
Casson, and the title of his lecture series was "The AndrewsCurtis and
the Poincare Conjectures". The invited speakers were Stephen Bigelow,
Martin Bridson, Danny Calegari, Nathan Dunfield, Cameron Gordon, Alan
Reid, Martin Scharlemann, Zlil Sela, and Peter Shalen. A special public
lecture was given by Jeff Weeks. There were also several contributed
talks. The organizers were Chaim GoodmanStrauss and Yo'av Rieck. The
conference was supported by NSF Grant DMS0245047 and by the Department
of Mathematical Sciences, Fulbright College of Arts and Sciences and
Graduate School of the University of Arkansas.
The second event was the Conference on the Topology of Manifolds of
Dimensions 3 and 4, held at the University of Texas at Austin, May 1921,
2003, in honor of the 60th birthday of Andrew Casson. Invited lectures
were given by Danny Calegari, Bob Edwards, Mike Freedman, Dave Gabai,
Rob Kirby, Greg Kuperberg, Darren Long, Peter Ozsvath, Andrew Ranicki,
Ron Stern, Peter Teichner, Kevin Walker, and Terry Wall. The organizing
committee consisted of Cameron Gordon, Bob Gompf, John Luecke and Alan
Reid. The conference was supported by NSF Grant DMS0229035 and by the
Department of Mathematics of the University of Texas at Austin.
