Zeta Functions of Lattices of the Symmetric Group

Abstract: The symmetric group $\mathfrak S_{n+1}$ of degree $n+1$ admits an $n$-dimensional irreducible $\mathbf Q \mathfrak S_n$-module $V$ corresponding to the hook partition $(2,1^{n-1})$. By the work of Craig and Plesken we know that there are $\sigma(n+1)$ many isomorphism classes of $\mathbf Z \mathfrak S_{n+1}$-lattices which are rationally equivalent to $V$, where $\sigma$ denotes the divisor counting function. In the present paper we explicitly compute the Solomon zeta function of these lattices. As an applicat… Show more

“…The concrete computation of zeta functions of ZG-lattices is in general a rather difficult problem, and not too much is known in this direction. The case where L is the regular ZG-lattice has been studied most intensively; for a list of known results see [6]. In [6], the second author determined the zeta functions ζ ZSn (L, s),…”

“…Bushnell and Reiner developed a method for calculating the Solomon zeta function for a Λ-lattice, where Λ is an integral order in a semisimple algebra over a p-adic field that makes use of ideas from Tate's thesis [5]. Since then this approach has been used by Wittmann to compute submodule zeta functions for the ZC p -lattice (ZC p ) n [18] and by Hofmann to compute the submodule zeta function for the Z-lattice corresponding to a ZS n+1 -module affording the irreducible character related to the hook partition (2, 1 n−1 ) [14]. The examples in this paper illustrate how to apply their technique to calculate, for any relevant prime p, the zeta function of Z p B where B is the Z-basis consisting of the standard basis of a commutative integral table algebra, a situation which includes the cases where B is a finite abelian group or the set of adjacency matrices of a commutative association scheme as special cases.…”
