Graphical methods and rings of invariants on the symmetric algebra

Rebecca Bourn, William Q. Erickson, Jeb F. Willenbring

Let $G$ be a complex classical group, and let $V$ be its defining representation (possibly plus a copy of the dual). A foundational problem in classical invariant theory is to writ…

Enright resolutions encoded by a generating function for Blattner's formula: Type A

William Q. Erickson

Consider the classical action of $GL_{n}$ on a sum of $q$ copies of the defining representation and $p$ copies of its dual; by Howe duality, the polynomial functions on this sp…

Contingency tables and the generalized Littlewood-Richardson coefficients

Mark Colarusso, William Q. Erickson, Jeb F. Willenbring

The Littlewood-Richardson coefficients $c_{μν}^{λ}$ give the multiplicity of an irreducible polynomial $GL_{n}$ -representation $F_{n}^{λ}$ in the tensor product of polynomial represe…
