Dirichlet motives via modular curves
Generalizing ideas of Anderson, Harder has proposed a construction of extensions of motives of Dirichlet-Tate type in sheaf theoretic terms (cf. [Ha] Section 4.2 or the review before Prop. 6.4). Let Mk(−1) be the smooth ladic sheaf on Y1(p) given as k-th symmetric power of the Tate module of the universal elliptic curve over Y1(p). Decomposing a certain l-adic cohomology group with coefficients...
متن کاملWeyl Group Multiple Dirichlet
Abstract. A Weyl group multiple Dirichlet series is a Dirichlet series in several complex variables attached to a root system Φ. The number of variables equals the rank r of the root system, and the series satisfies a group of functional equations isomorphic to the Weyl group W of Φ. In this paper we construct a Weyl group multiple Dirichlet series over the rational function field using n order...
متن کاملConstructing Weyl Group Multiple Dirichlet
Let Φ be a reduced root system of rank r. A Weyl group multiple Dirichlet series for Φ is a Dirichlet series in r complex variables s1, . . . , sr, initially converging for Re(si) sufficiently large, that has meromorphic continuation to C and satisfies functional equations under the transformations of C corresponding to the Weyl group of Φ. A heuristic definition of such series was given in [2]...
متن کاملDiscrete Heisenberg-Weyl Group and Modular Group
It is shown that the generators of two discrete Heisenberg-Weyl groups with irrational rotation numbers θ and −1/θ generate the whole algebra B of bounded operators on L2(R). The natural action of the modular group in B is implied. Applications to dynamical algebras appearing in lattice regularization and some duality principles are discussed. Writing a contribution to a memorial volume one alw...
متن کاملOn Dirichlet Series and Petersson Products for Siegel Modular Forms
— We prove that the Dirichlet series of Rankin–Selberg type associated with any pair of (not necessarily cuspidal) Siegel modular forms of degree n and weight k > n/2 has meromorphic continuation to C. Moreover, we show that the Petersson product of any pair of square–integrable modular forms of weight k > n/2 may be expressed in terms of the residue at s = k of the associated Dirichlet series....
