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…
The maximal discrete extension of for an imaginary-quadratic number field
Aloys Krieg, Joana Rodriguez, Annalena Wernz
Let be the ring of integers of an imaginary quadratic number field . In this paper we give a new description of the maximal discrete extension of t…
The graded ring of modular forms on the Cayley half-space of degree two
C. Dieckmann, A. Krieg, M. Woitalla
Hashimoto and Ueda determined the weights of generators of the graded ring of modular forms on the Cayley half-space of degree two. In this paper we describe explicit generators. W…
On the classification of lattices over $\Q(\sqrt{-3})$, which are even unimodular -lattices
Michael Hentschel, Aloys Krieg, Gabriele Nebe
We give a classification of the lattices of rank r=4, r=8 and r=12 over \Q(\sqrt{-3}), which are even and unimodular \Z-lattices. Using this classification we construct the associa…
