摘要:

对任意有理素数$p$,我们定义了全纯Siegel Eisenstein级数对任意亏格$n \ge 1$的辛群$\text{Sp}(2n)_{/\mathbb{Q}}$的某种$p$ -稳定化.此外,我们还导出了傅里叶系数的显式公式,并总结了它们的$p$ -adic插值问题。因此,对于任何奇素数$p$,我们推出了一个$Λ$ -adic形式(在A. Wiles,H. Hida和R.L. Taylor),使得在取适当的常数倍数后,同时插值上述$p$稳定的Siegel Eisenstein级数的$p$ -adic解析族和Siegel Eisenstein级数的$p$ -adic解析族,其中该级数在$p$处具有局部平凡的拟序特征标,在$p$处具有局部非平凡的拟序特征标.这可以看作是$\text{GL}(2)_{/\mathbb{Q}}$的普通$Λ$ -adic Eisenstein级数的一个非常自然的推广.

英文摘要:

For any rational prime $p$, we define a certain $p$-stabilization of holomorphic Siegel Eisenstein series for the symplectic group $\text{Sp}(2n)_{/\mathbb{Q}}$ of an arbitrary genus $n \ge 1$. In addition, we derive an explicit formula for the Fourier coefficients and conclude their $p$-adic interpolation problems. Consequently, for any odd prime $p$, we deduce the existence of a $Λ$-adic form (in the sense of A. Wiles, H. Hida and R.L. Taylor) such that after taking a suitable constant multiple, it interpolates $p$-adic analytic families of the above-mentioned $p$-stabilized Siegel Eisenstein series with nebentypus characters locally trivial at $p$ and Siegel Eisenstein series with nebentypus characters locally non-trivial at $p$ simultaneously. This can be viewed as a quite natural generalization of the ordinary $Λ$-adic Eisenstein series for $\text{GL}(2)_{/\mathbb{Q}}$.
