Derangement permutation matrices and orbit harmonics

Yupeng Li, Jasper Liu, Brendon Rhoades

The paper investigates the algebraic and representation-theoretic properties of the set of derangement permutation matrices via the orbit harmonics quotient ring, giving explicit g…

Involution matrix loci and orbit harmonics

Moxuan J. Liu, Yichen Ma, Brendon Rhoades +1

Let $Mat_{n \times n} (C)$ be the affine space of $n \times n$ complex matrices with coordinate ring $C [x_{n \times n}]$ . We define graded quotie…
