4:30 pm - 5:30 pm
Where: CMSA, 20 Garden St, G10
Address: 20 Garden Street, Cambridge, MA 02138, United States
Speaker: Daniel Wise - McGill University
Cube complexes have come to play an increasingly central role within geometric group theory, as their connection to right-angled Artin groups provides a powerful combinatorial bridge between geometry and algebra. This talk will introduce nonpositively curved cube complexes, and then describe the developments that culminated in  the resolution of the virtual Haken conjecture for 3-manifolds and  simultaneously dramatically extended our understanding of many  infinite groups.
