Abstract

G. Stevens (http://math.bu.edu/people/ghs/research.html) constructed a modular symbol taking values in circular K-groups, which is intimately related to Eisenstein series. We make precise a relationship between his Milnor K-theoretic modular symbol \(\Phi _{MK}\) and the period integrals of Eisenstein series. The main goal here is to extract from \(\Phi _{MK}\) a group 1-cocyle on \({{\mathrm{SL}}}_2(\mathbb {Q})\) with values in differential form valued distributions and use this to construct a p-adic locally analytic distribution which gives a p-adic partial zeta function of a real quadratic field.

Résumé

G. Stevens (http://math.bu.edu/people/ghs/research.html) a construit un symbole modulaire prenant ses valeurs dans un K-groupe circulaire, qui s’avère intimement relié aux séries d’Eisenstein. Nous décrivons une relation précise entre son symbole K-théorique \(\Phi _{MK}\) de Milnor et les périodes intégrales des séries d’Eisenstein. Notre objectif principal ici est d’extraire de \(\Phi _{MK}\) un groupe 1-cocycle sur \({{{\mathrm{SL}}}}_2(\mathbb {Q})\) à valeurs dans des distributions valuées de formes différentiables et de nous en servir pour construire une distribution analytique localement p-adique qui fournit une fonction zêta partielle p-adique d’un corps quadratique réel.

Notes

  1. The p-adic partial zeta functions of real quadratic fields (more generally, totally real fields) have been constructed by several people including Delinge–Ribet (using p-adic Hilbert modular forms and schemes), Pierre Cassou-Nougues (using Shintani’s formula), and Coates–Sinnott (using Siegel’s formula and stickelberger element only for real quadratic case). Here we mean a way of constructing them directly via the period integrals of Eisenstein series.

This article is dedicated to my teacher Glenn Stevens for his 60th birthday conference. Throughout the article, it should be clear to the readers that the existence of this paper owes pretty much to Glenn Stevens’s insight on modular symbols, Eisenstein series, p-adic L-functions, and Milnor K-symbols. I would like to express my deepest thanks to Glenn Stevens. Without his constant help and encouragement, this article simply could not exist. I also thank the anonymous referee for helpful comments.
