Eisenstein series for O(2,n+2)
Aloys Krieg, Felix Schaps, Hannah Römer
We will characterize the Eisenstein series for O(2, n + 2) as a particular Hecke eigenform. As an application we show that it belongs to the associated Maaß space. If the underlyin…
On Hermitian Eisenstein series of degree 2
Adrian Hauffe-Waschbüsch, Aloys Krieg, Brandon Williams
We consider the Hermitian Eisenstein series of degree and weight associated with an imaginary-quadratic number field and determine the inf…
The Hilbert Modular Group and Orthogonal Groups
Adrian Hauffe-Waschbüsch, Aloys Krieg
We derive an explicit isomorphism between the Hilbert modular group and certain congruence subgroups on the one hand and particular subgroups of the special orthogonal group $SO(2,…
Maximal Discrete Subgroups of
Aloys Krieg, Felix Schaps
We characterize the maximal discrete subgroups of , which contain the discriminant kernel of an even lattice, which contains two hyperbolic planes over . T…
Congruence Subgroups and Orthogonal Groups
Adrian Hauffe-Waschbüsch, Aloys Krieg
We derive explicit isomorphisms between certain congruence subgroups of the Siegel modular group, the Hermitian modular group over an arbitrary imaginary-quadratic number field and…
On Hecke theory for Hermitian modular forms
Adrian Hauffe-Waschbüsch, Aloys Krieg
In this paper we outline the Hecke theory for Hermitian modular forms in the sense of Hel Braun for arbitrary class number of the attached imaginary-quadratic number field. The Hec…
