GL‐algebras in positive characteristic II: The polynomial ring

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 6, December 2025.
Abstract We study GL$\mathbf {GL}$‐equivariant modules over the infinite variable polynomial ring S=k[x1,x2,…,xn,…]$S = k[x_1, x_2, \ldots, x_n, \ldots]$ with k$k$ an infinite field of characteristic p>0$p > 0$. We extend many of Sam–Snowden's far‐reaching results from characteristic zero to this setting.

Approximation of subcategories by abelian subcategories

open access: yes, 2016
Let $\mathcal{C}$ be an abelian category and let $\Lambda : \mathcal{C}\rightarrow\mathcal{C}$ be an idempotent functor which is not right exact, so that the zeroth left derived functor $L_0\Lambda$ does not necessarily coincide with $\Lambda$.
