Decomposing induced characters of the centralizer of an $n$-cycle in the symmetric group on $2n$-elements

Abstract

We give explicit multiplicities and formulas for multiplicities of characters appearing in the decomposition of the induced character Ind^{S_{2n}}_{C_{S_{2n}}(σ)} 1_C, where σ is an n-cycle, C_{S_{2n}}(σ) is the centralizer of σ in S_{2n}, and 1_C denotes the trivial character on C_{S_{2n}}(σ).
