$Γ_g(1,2)$的权为8的模形式

Modular Forms of weight 8 for $Γ_g(1,2)$

M. Oura, C. Poor, R. Salvati Manni, D. Yuen

摘要:

通过证明权为8的Siegel尖点形式对Jacobian的限制满足Anstaz定理,完成了D 'Hoker和Phong的Anstaz定理在亏格~4中所表示的程序.我们证明了$\dim [Γ_4(1,2),8]_0=2$和$\dim [Γ_4(1,2),8]=7$ .在每个亏格中,我们对秩为{16}的自对偶格之间的线性关系进行了分类。我们通过构造满足上述条件的θ级数的唯一线性组合,将程序推广到亏格5。

英文摘要:

We complete the program indicated by the Ansatz of D'Hoker and Phong in genus ~4 by proving the uniqueness of the restriction to Jacobians of the weight 8 Siegel cusp forms satisfying the Anstaz. We prove $\dim [Γ_4(1,2),8]_0=2$ and $\dim [Γ_4(1,2),8]=7$. In each genus, we classify the linear relations among the self-dual lattices of rank {16}. We extend the program to genus ~5 by constructing the unique linear combination of theta series that satisfies the Ansatz.
