Equidistribution of exponential sums indexed by a subgroup of fixed cardinality
Résumé
We consider families of exponential sums indexed by a subgroup of invertible classes modulo some prime power q. For fixed d , we restrict to moduli q so that there is a unique subgroup of invertible classes modulo q of order d. We study distribution properties of these families of sums as q grows and we establish equidistribution results in some regions of the complex plane which are described as the image of a multi-dimensional torus via an explicit Laurent polynomial. In some cases, the region of equidistribution can be interpreted as the one delimited by a hypocycloid, or as a Minkowski sum of such regions.
