摘要:

我们推导了酉群某些标准Langlands $L$-函数中阿基米德欧拉因子的精确公式。在1980年代,Paul Garrett以及Ilya Piatetski-Shapiro和Stephen Rallis(独立于Garrett)发现了自守$L$-函数的积分表示,这些表示是欧拉型的,但与Rankin--Selberg和Langlands--Shahidi方法不同,它们不要求$L$-函数所关联的自守表示是全局通用的。他们的方法,即加倍方法,为先前方法无法处理的多种应用打开了大门。然而,三十多年来,酉群在阿基米德位置的欧拉因子中出现的积分一直难以精确计算,除非在特定简化条件下(例如要求某些表示是一维的,正如Garrett在这一计算的首个重大进展以及唯一对一般符号的先前进展中所做的那样)。我们计算了任意符号酉群的一般向量权全纯离散级数的这些积分。这不仅对阿基米德情形下$L$-函数的特殊值有影响,也对$p$-进$L$-函数有影响,其中相应的项此前一直未解决。

英文摘要:

We derive precise formulas for the archimedean Euler factors occurring in certain standard Langlands $L$-functions for unitary groups. In the 1980s, Paul Garrett, as well as Ilya Piatetski-Shapiro and Stephen Rallis (independently of Garrett), discovered integral representations of automorphic $L$-functions that are Eulerian but, in contrast to the Rankin--Selberg and Langlands--Shahidi methods, do not require that the automorphic representations to which the $L$-functions are associated are globally generic. Their approach, the doubling method, opened the door to a variety of applications that could not be handled by prior methods. For over three decades, though, the integrals occurring in the Euler factors at archimedean places for unitary groups eluded precise computation, except under particular simplifications (such as requiring certain representations to be one-dimensional, as Garrett did in the first major progress on this computation and only prior progress for general signatures). We compute these integrals for holomorphic discrete series of general vector weights for unitary groups of any signature. This has consequences not only for special values of $L$-functions in the archimedean setting, but also for $p$-adic $L$-functions, where the corresponding term had remained open.
