Elementary divisors of Specht modules
Matthias Künzer, Andrew Mathas
Let H_q(S_n) be the Iwahori-Hecke algebra of the symmetric group. This algebra is semisimple over the rational function field Q(q), where q is an indeterminate, and its irreducible…

Elementary divisors of Gram matrices of certain Specht modules
Matthias Kuenzer, Gabriele Nebe
The elementary divisors of the Gram matrices of Specht modules S^lambda over the symmetric group are determined for two-row partitions and for two-column partitions lambda. More pr…

On the cyclotomic Dedekind embedding and the cyclic Wedderburn embedding
Harald Weber, Matthias Kuenzer
Let n >= 1 and let p be a prime. Let t = 1 - zeta_{p^n}. Expand an integer j in [0,p^n-1], coprime to p, p-adically as j = sum_{s >= 0} a_s p^s. Denote the tensor product over Z_(p…
