The Department of Mathematics will host the Conference on Low-Dimensional Topology and Geometry from May 15 to 19, 2017. Held in conjunction with the 32nd Annual Shanks Lecture, the conference will focus on the close interrelationships between geometry and topology in low dimensions, such as in the study of surfaces and three-dimensional manifolds (3-manifolds). Emphasis will be on the powerful negative curvature and combinatorial techniques that are driving much of the current research in this area.

The inherent connection between geometry and topology pervaded William Thurston’s revolutionary work in the 1980s that refocused the field of 3-manifold topology around a handful of bold geometric conjectures. By drawing on the work of many mathematicians and incorporating wide-ranging ideas from ergodic theory, combinatorial geometry, hyperbolic geometry, and group theory, this new paradigm in 3-manifold topology has recently culminated in the proof of Thurston’s virtual fibering conjecture.

The Vanderbilt conference will revisit some of the ideas that emerged from these developments and examine the tools and techniques that are now being refined and applied to broader contexts. Topics will include hyperbolic 3-manifolds, moduli spaces of Riemann surfaces, the geometry and topology of curves on surfaces, surface bundles, Gromov-hyperbolic simplicial complexes, CAT(0) cube complexes, and many others.

This year’s featured Shanks Lecturer is Professor Ian Agol of the University of California, Berkeley. Agol received the 2016 Breakthrough Prize in Mathematics for his contributions to low-dimensional topology and geometric group theory, including work on the solutions of the tameness, virtual Haken, and virtual fibering conjectures. Agol is also the recipient of the 2013 Oswald Veblen Prize in Geometry and the 2009 Clay Research Award.

The prestigious Shanks Lecture Series is organized annually by the Department of Mathematics of Vanderbilt University, honoring Baylis and Olivia Shanks. The late Professor Baylis Shanks was chairman of the Department from 1955 through 1969. A list of previous Shanks Conferences and Lecturers can be found here.
