Let be a finite field extension. The Langlands correspondence gives a canonical bijection between the set of equivalence classes of irreducible -dimensional representations of the Weil group of and the set of equivalence classes of irreducible supercuspidal representations of GL. This paper is concerned with the case where . In earlier work, the authors constructed an explicit bijection using a non-Galois tame base change map. If this tame base change satisfies a certain conjectured...
In this paper we study three new shifted sums of Apostol-Dedekind-Rademacher type. The first sums are written in terms of Jacobi modular forms, and the second sums in terms of cotangent and the third sums are expressed in terms of special values of the Barnes multiple zeta functions. These sums generalize the classical Dedekind-Rademacher sums. The main aim of this paper is to state and prove the Dedekind reciprocity laws satisfied by these new sums. As an application of our Dedekind reciprocity...
