Geometric Group Theory and Topology Seminar

Geometric group theory and topology (GGTT) at Tufts includes topics in geometric topology (especially in dimensions 2 and 3) and the geometry of finitely generated groups. Areas of interest include hyperbolicity and metric nonpositive curvature, braids and mapping class groups, lattices and buildings, dynamics of group actions, and asymptotic geometry.

The seminar meets weekly on Tuesdays at 4:30pm unless otherwise noted, in Room 404, 574 Boston Ave.

This building is at the corner of Boston and Harvard. There is visitor parking in the lot on Boston Ave. The Harvard Ave. door requires a Tufts University ID to open, the Boston Ave. (parking lot) door stays open until 5 pm.
