与$Γ_0(2)$有关的爱森斯坦级数

Eisenstein series associated with $Γ_0(2)$

Heekyoung Hahn

摘要:

本文定义了规范化Eisenstein级数$\mathcal{P}$、$e$和与$Γ_0(2),$相关的$\mathcal{Q}$,并由三角恒等式导出了它们所满足的三个微分方程.利用这三个公式,我们定义了一个依赖于$Γ_0(2)$上模形式权的微分方程,然后利用正交多项式和高斯超几何级数构造了它的模解.我们还构造了一类与三角数有关的无穷级数。最后,我们从一个涉及三角数的公式中导出了一个组合恒等式。

英文摘要:

In this paper, we define the normalized Eisenstein series $\mathcal{P}$, $e$, and $\mathcal{Q}$ associated with $Γ_0(2),$ and derive three differential equations satisfied by them from some trigonometric identities. By using these three formulas, we define a differential equation depending on the weights of modular forms on $Γ_0(2)$ and then construct its modular solutions by using orthogonal polynomials and Gaussian hypergeometric series. We also construct a certain class of infinite series connected with the triangular numbers. Finally, we derive a combinatorial identity from a formula involving the triangular numbers.
