On Orbits of Order Ideals of Minuscule Posets
Published 2013-01-01“…An action on order ideals of posets considered by Fon-Der-Flaass is analyzed in the case of posets arising from minuscule representations of complex simple Lie algebras. For these minuscule posets, it is shown that the Fon-Der-Flaass action exhibits the cyclic sieving phenomenon, as defined by Reiner, Stanton, and White. …”

Recurrence relations and path representations of matrix elements of an SU(1,1) algebra
Published 2013“…A normal ordered representation of a Unitary operator $U$ constructed from the generators of a SU(1,1) algebra, which is a generalisation of the Baker- Campbell - Hausdorff relation for Lie algebras, is given. It is shown that the normal ordered representatiion of $U$ may be used to calculate expectation values which are functions of the parameters used to construct the operator. …”

Fun with F24
Published 2021-02-01“…The models depend on the choice of an N $$ \mathcal{N} $$ = 1 supercurrent on F 24, with the admissible choices labeled by the semisimple Lie algebras of dimension 24. We also discuss how F 24, with any such choice of supercurrent, can be obtained via orbifolding from another distinguished c = 12 holomorphic SCFT, the N $$ \mathcal{N} $$ = 1 supersymmetric version of the chiral CFT based on the E 8 lattice.…”
