개요

  • $E_k$는 weight $k$인 지겔-아이젠슈타인 급수
  • cusp form $X_{10},X_{12},X_{35}$
  • $E_4, E_6, X_{10},X_{12}, X_{35}$는 $\mathbb{C}$-algebra $M(\Gamma_2)$를 생성


생성원

  • $x_{10}=E_4E_6-E_{10}$, weight 10 cusp form
  • $x_{12}=441E_4^3+250E_6^2-691E_{12}$, weight 12 cusp form
  • $X_{10},X_{12}$는 $a(X_{k};(1,1,1))=1$를 만족하는 $x_{10},x_{12}$의 상수배, 즉

$$ \begin{aligned} X_{10}&=\zeta q_1 q_2+\frac{q_1 q_2}{\zeta }-2 q_1 q_2+\cdots \\ X_{12}&=\zeta q_1 q_2+\frac{q_1 q_2}{\zeta }+10 q_1 q_2+\cdots \end{aligned} $$

  • There exists a weight 35 cusp form $X_{35}$;we normalize $X_{35}$ so that $a(X_{35};(2,-1,3))=1$
  • $E_4, E_6, X_{10},X_{12}$ are algebraically independent over $\mathbb{C}$
  • $E_4, E_6, X_{10},X_{12}, X_{35}$ have integral Fourier coefficients
