Quantized nilradicals of parabolic subalgebras of $\mathfrak{sl}(n)$ and algebras of coinvariants

Andrew Jaramillo, Garrett Johnson

Let $P_J$ be the standard parabolic subgroup of $S{L}_n$ obtained by deleting a subset $J$ of negative simple roots, and let $P_J=L_J{U}_J$ be the standard Levi decomposition. Follow…
