论文摘要
我们在西格尔模块化组的某些一致性亚组，在任意虚构的二次数字领域中的某些一致性亚组，Hermitian模块化组与2度的Hurwitz Quaternions的模块组和模块化组之间的显式同构，以及在Hurwitz quaternions y hurwitz quaternions y hurwitz quaternions of Hurwitz quaternions of Hurwitz quaternions of 2 Quaternions of 2 Quaternions of 2 Quaternions coptimenter lingle lingle line kernels line kernels line line line line so的启用（2，n = 3，n = 3，4 = 3，4，4。适应数字理论需求。
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 the modular group over the Hurwitz quaternions of degree 2 and the discriminant kernels of special orthogonal groups SO 0 (2, n), n = 3, 4, 6. The proof is based on an application of linear algebra adapted to the number theoretical needs.
