Hilbert modular group
WebApr 6, 2024 · In this paper we give a new proof of the result of Brunault and Neuruer as well as a substantial generalisation (to the case of Hilbert modular forms) using adelic and local representation-theoretic methods. Specifically we use local Whittaker functions and their invariance properties.

Webextension of the notion of modular forms to other groups. An example of this is the step from SL (2,Z ) to the group SL (2, O K) with O K the ring of inte-gers of a totally real eld, the Hilbert modular group. Hilbert was inspired by Kronecker s Jugendtraum about generating abelian extensions of imaginary quadratic elds. WebHilbert modular surfaces are a generalization of modular curves, and one of the more concrete examples of Shimura varieties. They are formed by taking the product of two copies of the upper half plane and quotienting by a Hilbert modular group arising from a real quadratic eld. This produces a complex surface which is neither smooth nor compact ...

Congruence coverings of M. If I ⊂ O is an ideal, the natural projection O → O/I induces a group homomorphism SL2(O) −→πI SL 2(O/I). Let us denote by Γ(I) := ker(πI) the principal congruence subgroup of Γ associated to I.
