Organizing Committee

Dehn surgery has played a central role in the development of low-dimensional topology since it was first introduced by Max Dehn in 1910. Its study has stimulated several fascinating techniques that incorporate ideas from across mathematics: hyperbolic geometry, representation varieties, combinatorics, sutured manifold theory, and Floer homology, to name a few. These tools have led to sensational progress in understanding problems about Dehn surgery and low-dimensional topology at large. Furthermore, they seem well-suited to attack the major open problems in the area, such as the Berge conjecture and the L-space conjecture.

The workshop will function as a graduate summer school. At its core, the school will feature a sequence of mini-courses delivered by a cast of leading experts and distinguished expositors. The courses will unveil Dehn surgery and this suite of techniques to the next generation of researchers in the area. The school will additionally feature guided problem sessions and special presentations on the important role that computation has played and will continue to play in the field.

While targeted at graduate students, the school welcomes applications from qualified future and former graduate students, as well. The main goal will be to enjoy a stimulating week of exploration around a fascinating and active area.

The five mini-courses will be led by Steve Boyer, Cameron Gordon, Marc Lackenby, Yi Ni, and Rachel Roberts.

This workshop is partially supported by NSF CAREER Award DMS-1455132. Please request the funding that you would require in order to be able to attend. Please disregard the standard language on the ICERM application page concerning limited graduate student funding. In particular, you do not need to prepare a poster to be eligible for funding.

For full consideration for funding, please apply no later than March 30, 2019.
