In this work, we study the expansion of a product function U related to the Drinfeld discriminant 2(z); U is the analogue of the classical '-function. The main result is the formula given in Theorem 3.1. From this formula, we derive the fact that the expansion of U is lacunary for q>2 (Theorem 3.3)

Let \(k\) be a global function field with constant field \(\mathbb{F}_{q}\). Let \(\infty\) be a place of \(k\) and let \(\mathbb{c}_{k}\) be the ring of functions regular outside of \(\propto\). Once a sign function has been chosen, one can define a discriminant function on the set of rank 1 Drinfe

We show that functions of two complex variables which are symmetric and holomorphic on suitable domains can be expanded in locally uniform convergent series of products of LamΓ© polynomials. The result is based on a more general expansion theorem for holomorphic functions defined on a two-dimensional
