Homological stability for families of groups

Connections for Women: Algebraic Topology January 23, 2014 - January 24, 2014

January 23, 2014 (02:30 PM PST - 03:30 PM PST)
Speaker(s): Nathalie Wahl (University of Copenhagen)
Location: MSRI: Simons Auditorium


Symmetric groups, braid groups, certain mapping class groups and general linear groups are examples of families of groups known to display a stability phenomenon in their homology. In my talks, I will give an answer to the following questions: What do these examples have in common? When should one expect that a family of groups satisfies homological stability? and how does one check that such a family does indeed stabilize?
