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. important characters in king arthur

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. If R is the ring of integers of a real quadratic field, then the Hilbert modular group SL2(R) acts on the product H×H of two copies of the upper half plane H. There are several birationally equivalent surfaces related to this action, any of which may be called Hilbert modular surfaces: • The surface X is the quotient of H×H by SL2(R); it is not compact and usually has quotient singularities coming from points with non-trivial isotropy groups.
