Algebra Seminar

Algebraic completions of discrete and profinite groups

Richard Hain

6th November, 12:05-12:55pm, Carslaw 159 (*** NOTE THURSDAY NOT FRIDAY ***)


Abstract

This talk will survey various algebraic completions of discrete and profinite groups. Motivation from topology and algebraic/arithmetic geometry will be given for studying these completions. Examples from Galois theory and geometric topology (braid groups, mapping class groups, Torelli groups) will be given.


After the seminar we will take the speaker to lunch.

See the Algebra Seminar web page for information about other seminars in the series.
