Rational singularities of $G$ -saturation

Nham V. Ngo

Let $G$ be a semisimple algebraic group defined over an algebraically closed field of characteristic 0 and $P$ be a parabolic subgroup of $G$ . Let $M$ be a $P$ -module and $V$ be a…

Reducibility of nilpotent commuting varieties

Robert M. Guralnick, Nham V. Ngo

Let $N_{n}$ be the set of nilpotent $n$ by $n$ matrices over an algebraically closed field $k$ . For each $r \geq 2$ , let $C_{r} (N_{n})$ be the variety consisting of all pairwise commutin…

On varieties of commuting nilpotent matrices

Nham V. Ngo, Klemen Šivic

Let $N (d, n)$ be the variety of all $d$ -tuples of commuting nilpotent $n \times n$ matrices. It is well-known that $N (d, n)$ is irreducible if $d = 2$ , if $n \leq 3$ or if $d = 3$ and $n = 4$ …

Mixed Commuting Varieties over simple Lie algebras

Nham V. Ngo

Let $g$ be a simple Lie algebra defined over an algebraically closed field $k$ of characteristic $p$ . Fix an integer $r > 1$ and suppose that $V_{1}, \dots, V_{r}$ are irreduci…
