A new approach to twisted homological stability, with applications to congruence subgroups
Andrew Putman
We introduce a new method for proving twisted homological stability, and use it to prove such results for symmetric groups and general linear groups. In addition to sometimes sligh…

The Steinberg representation is irreducible
Andrew Putman, Andrew Snowden
We prove that the Steinberg representation of a connected reductive group over an infinite field is irreducible. For finite fields, this is a classical theorem of Steinberg and Cur…

The commutator subgroups of free groups and surface groups
Andrew Putman
A beautifully simple free generating set for the commutator subgroup of a free group was constructed by Tomaszewski. We give a new geometric proof of his theorem, and show how to g…
