modules in non-describing characteristic, Part I
Rohit Nagpal
Let be the category of finite dimensional -vector spaces whose morphisms are injective linear maps, and let be a noetherian ring. We study…
Linear and quadratic ranges in representation stability
Thomas Church, Jeremy Miller, Rohit Nagpal +1
We prove two general results concerning spectral sequences of -modules. These results can be used to significantly improve stable ranges in a large portion of the stab…
Periodicity in the cohomology of symmetric groups via divided powers
Rohit Nagpal, Andrew Snowden
A famous theorem of Nakaoka asserts that the cohomology of the symmetric group stabilizes. The first author generalized this theorem to non-trivial coefficient systems, in the form…
Regularity of FI-modules and local cohomology
Rohit Nagpal, Steven V Sam, Andrew Snowden
We resolve a conjecture of Li and Ramos that relates the regularity of an FI-module to its local cohomology groups. This is an analogue of the familiar relationship between regular…
