WebThe moduli spaces of such abelian surfaces are Hilbert modular surfaces. Since the moduli spaces of polarized complex abelian varieties are Siegel modular varieties we find natural maps of Hilbert modular surfaces to Siegel modular threefolds. WebOct 14, 2003 · Borcherds products and arithmetic intersection theory on Hilbert modular surfaces Jan H. Bruinier, Jose I. Burgos Gil, Ulf Kuehn We prove an arithmetic version of a theorem of Hirzebruch and Zagier saying that Hirzebruch-Zagier divisors on a Hilbert modular surface are the coefficients of an elliptic modular form of weight two.

Webthe modular curve into the Hilbert modular sur-face. We have SL2(Z) ,→ SL2(O F) and h,→ h × h giving rise to SL2(Z)\h,→ SL2(O F)\(h × h). More generally, we can work with a congruence subgroup. The projection of these cycles to each π component produces a Tate class in each IH2(π) for which πis a lift. Embedding the modular curve ... WebDans cet article, nous étudions la théorie d’Iwasawa pour les formes modulaires de Hilbert sur l’extension anticyclotomique d’un champ CM. Nous prouvons un résultat de divisibilité unilatérale vers la conjecture principale d’Iwasawa dans ce cadre. irish infinity symbol
