关于整体函数域上的Kronecker项

On Kronecker terms over global function fields

Fu-Tsun Wei

摘要:

本文建立了以Drinfeld周期域为上半平面的整体函数域上任意秩的广义Kronecker极限公式。Drinfeld-Siegel单位作为等价的特征模形式取代了经典的$Δ$。这导致分析手段推导出的Colmez型公式的“稳定田口高度”的CM Drinfeld模块具有任意的秩。在Bruhat-Tits建筑物的Heegner圈的介入下,得到了“全实”函数场的Lerch型公式.我们的极限公式也自然地适用于Rankin-Selberg $L$ -函数和Godement-Jacquet $L$ -函数的特殊值与自守尖形表示在整体函数域。

英文摘要:

We establish a general Kronecker limit formula of arbitrary rank over global function fields with Drinfeld period domains playing the role of upper-half plane. The Drinfeld-Siegel units come up as equal characteristic modular forms replacing the classical $Δ$. This leads to analytic means of deriving a Colmez-type formula for "stable Taguchi height" of CM Drinfeld modules having arbitrary rank. A Lerch-Type formula for "totally real" function fields is also obtained, with the Heegner cycle on the Bruhat-Tits buildings intervene. Also our limit formula is naturally applied to the special values of both the Rankin-Selberg $L$-functions and the Godement-Jacquet $L$-functions associated to automorphic cuspidal representations over global function fields.
