Abstract We show that a Siegel modular form with integral Fourier coefficients in a number field K, for which all but finitely many coefficients (up to equivalence) are divisible by a prime ideal 𝔭

Quasi-coherent sheaves on the moduli stack of formal groups
The central aim of this monograph is to provide decomposition results for quasi-coherent sheaves on the moduli stack of one-dimensional formal groups. These results will be based on the geometry of
Automata and transcendence of the Tate period in finite characteristic
• Mathematics
• 1999
Using the techniques of automata theory, we give another proof of the function field analogue of the Mahler-Manin conjecture and prove transcendence results for the power series associated to higher
On smooth plane models for modular curves of Shimura type
• Mathematics
• 2022
. In this paper we prove that there are ﬁnitely many modular curves that admit a smooth plane model. Moreover, if the degree of the model is greater than or equal to 10 , no such curve exists. For

We show that the completed Hecke algebra of $p$-adic modular forms is isomorphic to the completed Hecke algebra of continuous $p$-adic automorphic forms for the units of the quaternion algebra
Mod p modular forms and simple congruences
• Mathematics

In this article, we first give a complete description of the algebra of integer weight modular forms on the congruence subgroup $$\Gamma _0(2)$$ modulo a prime $$p\ge 3$$ . This result parallels

Perfectoid geometry of p-adic modular forms
We prove a perfectoid tilting isomorphism that describes the Hecke module of overconvergent t-adic modular forms of Andreatta–Iovita–Pilloni at the boundary of weight space in terms of p-th power

Soient K un corps de nombres algebriques totalement reel, et ζK sa fonction zeta. D’apres un theoreme de Siegel [24], ζK(1 − k) est un nombre rationnel si k est entier ⩾ 1; il est ≠ 0 si k est pair.

The work I shall describe in these lectures has two themes, a classical one going back to Ramanujan [8] and a modern one initiated by Serre [9] and Deligne [3]. To describe the classical theme, let
