Ayşe Alaca, Şaban Alaca, Zafer Selcuk Aygin

摘要:

我们找到了模形式空间$M_2\Big(Γ_0(24),\Big(\frac{d}{\cdot}\Big)\Big)$($d=1,8,12, 24$)的基.我们确定的所有$35$ θ产品$φ[a_1,a_2,a_3,a_4](z)$在这些空间中的傅立叶系数。然后我们推导出正整数$n$的对角四元二次型的系数$1$,$2$,$3$或$6$的表示数的公式,以统一的方式,其中$14$是Ramanujan的通用四元二次型。我们还找到了Eisenstein空间$E_2\Big(Γ_0(24),\Big(\frac{d}{\cdot}\Big)\Big)$($d=1,8,12,24$)中的所有η子,并给出了它们的Fourier系数.

英文摘要:

We find bases for the spaces $M_2\Big(Γ_0(24),\Big(\frac{d}{\cdot}\Big)\Big)$ ($d=1,8,12, 24$) of modular forms. We determine the Fourier coefficients of all $35$ theta products $φ[a_1,a_2,a_3,a_4](z)$ in these spaces. We then deduce formulas for the number of representations of a positive integer $n$ by diagonal quaternary quadratic forms with coefficients $1$, $2$, $3$ or $6$ in a uniform manner, of which $14$ are Ramanujan's universal quaternary quadratic forms. We also find all the eta quotients in the Eisenstein spaces $E_2\Big(Γ_0(24),\Big(\frac{d}{\cdot}\Big)\Big)$ ($d=1,8,12,24$) and give their Fourier coefficients.
