Polynomial Expressions for Symmetric Group Characters on Cycles

Combinatorics 2026-01-26 v1

Abstract

In \cite{[CZ]}, Cohen and Zemel showed that for a partition λk\lambda \vdash k, the dimension of the irreducible representation of SnS_{n} corresponding to the partition (nk,λ)n(n-k,\lambda) \vdash n is a polynomial of degree kk in nn, whose coefficients in the binomial basis count standard Young tableaux of shape λ\lambda with special restrictions. In this paper, we generalize their results on the representation's dimension to character values on arbitrary cycles.
