A Littlewood-type identity for Robbins polynomials
Ilse Fischer, Hans Höngesberg
We provide a generalization of the Littlewood identity, both sides of which are related to alternating sign matrices. The classical Littlewood identity establishes a nice product f…

A generalization of conjugation of integer partitions
Seamus Albion, Theresia Eisenkölbl, Ilse Fischer +4
We exhibit, for any positive integer parameter , an involution on the set of integer partitions of . These involutions show the joint symmetry of the distributions of the fol…

Skew symplectic and orthogonal characters through lattice paths
Seamus P. Albion, Ilse Fischer, Hans Höngesberg +1
The skew Schur functions admit many determinantal expressions. Chief among them are the (dual) Jacobi-Trudi formula and the Lascoux-Pragacz formula, which is a skew analogue of the…
