Characters and projective characters of alternating and symmetric groups determined by values on -classes
Eoghan McDowell
This paper identifies all pairs of ordinary irreducible characters of the alternating group which agree on conjugacy classes of elements of order not divisible by a fixed integer $…
Modular plethystic isomorphisms for two-dimensional linear groups
Eoghan McDowell, Mark Wildon
Let be the natural representation of the special linear group over an arbitrary field . We use the two dual constructions of the symmetric power when …
The image of the Specht module under the inverse Schur functor in arbitrary characteristic
Eoghan McDowell
This paper gives a necessary and sufficient condition for the image of the Specht module under the inverse Schur functor to be isomorphic to the dual Weyl module in characteristic…
Flagged Schur polynomial duality via a lattice path bijection
Eoghan McDowell
This paper proves an identity between flagged Schur polynomials, giving a duality between row flags and column flags. This identity generalises both the binomial determinant dualit…
A random walk on the indecomposable summands of tensor products of modular representations of
Eoghan McDowell
In this paper we introduce a novel family of Markov chains on the simple representations of in defining characteristic, defined by tensoring with a fi…
