Can a Drinfeld Module Be Modular?

چکیده
Let k be a global function field with field of constants Fr, r = p m, and let ∞ be a fixed place of k. In his habilitation thesis [Boc2], Gebhard Böckle attaches abelian Galois representations to characteristic p valued cusp eigenforms and double cusp eigenforms [Go1] such that Hecke eigenvalues correspond to the image of Frobenius elements. In the case where k = Fr(T ) and ∞ corresponds to the pole of T , it then becomes reasonable to ask whether rank 1 Drinfeld modules over k are themselves “modular” in that their Galois representations arise from a cusp or double cusp form. This paper gives an introduction to [Boc2] with an emphasis on modularity and closes with some specific questions raised by Böckle’s work.

2 2 N ov 2 00 4 DRINFELD MODULAR CURVE AND WEIL PAIRING
In this paper we describe the compactification of the Drin-feld modular curve. This compactification is analogous to the compact-ification of the classical modular curve given by Katz and Mazur. We show how the Weil pairing on Drinfeld modules that we defined in earlier work gives rise to a map on the Drinfeld modular curve. We introduce the Tate-Drinfeld module and show how this describes the ...

These notes continue the notes of Anand Pillay on model theory and diophantine geometry. In my lectures I describe a model theoretic approach to some analogues of the Mordell-Lang conjecture for Drinfeld modules. Many questions remain open and algebraic proofs along the lines of the proof of the Manin-Mumford conjecture described by Pillay may be possible. We discuss these questions and potenti...
متن کامل3 More Properties of Yetter - Drinfeld Modules over Quasi - Hopf Algebras
We generalize various properties of Yetter-Drinfeld modules over Hopf algebras to quasi-Hopf algebras. The dual of a finite dimensional Yetter-Drinfeld module is again a Yetter-Drinfeld module. The algebra H 0 in the category of Yetter-Drinfeld modules that can be obtained by modifying the multiplication in a proper way is quantum commutative. We give a Structure Theorem for Hopf modules in the...
متن کاملOn duality of modular G-Riesz bases and G-Riesz bases in Hilbert C*-modules
In this paper, we investigate duality of modular g-Riesz bases and g-Riesz bases in Hilbert C*-modules. First we give some characterization of g-Riesz bases in Hilbert C*-modules, by using properties of operator theory. Next, we characterize the duals of a given g-Riesz basis in Hilbert C*-module. In addition, we obtain sufficient and necessary condition for a dual of a g-Riesz basis to be agai...
متن کاملEquidistribution and Integral Points for Drinfeld Modules
We prove that the local height of a point on a Drinfeld module can be computed by averaging the logarithm of the distance to that point over the torsion points of the module. This gives rise to a Drinfeld module analog of a weak version of Siegel’s integral points theorem over number fields and to an analog of a theorem of Schinzel’s regarding the order of a point modulo certain primes.
