Defining Equations of Nilpotent Orbits for Borel Subgroups of Modality Zero in Type $A_n$

Madeleine Burkhart, David Vella

Let $G$ be a quasi-simple algebraic group defined over an algebraically closed field $k$ and $B$ a Borel subgroup of $G$ acting on the nilradical $\mathfrak{n}$ of its Lie algebra…
