Around two dozen students and faculty attended the L2 seminar, an annual one day mini-conference in geometry and topology held in the department. Speaking at the conference were

Jason Manning (Cornell) — Boundaries of hyperbolic and relatively hyperbolic groups
Thomas Church (Stanford/IAS) — Stability and vanishing in the unstable cohomology of SLn(Z)
Emily Dryden (Bucknell) — Recovering geometric and topological information from oscillation frequencies
Renato Bettiol (University of Pennsylvania) — Deforming flat manifolds and flat orbifolds
