Bhargava Integer Cubes and Weyl Group Multiple Dirichlet Series

Abstract

We investigate the Shintani zeta functions associated to the prehomogeneous spaces, the example under consideration is the set of $2\times 2\times 2$ integer cubes. We show that there are three relative invariants under a certain parabolic group action, they all have arithmetic nature and completely determine the equivalence classes. We show that the associated Shintani zeta function coincides with the $A_3$ Weyl group multiple Dirichlet series. Finally, we show that the set of semi-stable integer orbits maps finitely and surjectively to a certain moduli space.
