对于本原非平凡Dirichlet特征标[Formula:see text]和[Formula:see text],我们研究了在[Formula:see text]上的权为零的新形式Eisenstein级数[Formula:see text].这个函数的全纯部分有一个变换规则,我们用有限项表示为广义戴德金和。这就产生了[公式:见正文]元素的显式构造(有限项)。我们也给出了一个简短的证明,这个戴德和的互易公式。
For primitive nontrivial Dirichlet characters [Formula: see text] and [Formula: see text], we study the weight zero newform Eisenstein series [Formula: see text] at [Formula: see text]. The holomorphic part of this function has a transformation rule that we express in finite terms as a generalized Dedekind sum. This gives rise to the explicit construction (in finite terms) of elements of [Formula: see text]. We also give a short proof of the reciprocity formula for this Dedekind sum.
