Gross-Zagier 공식

  • \(d_1, d_ 2\)가 서로 다른 두 복소이차수체 \(K_1, K_2\)의 판별식이라 하자.
  • \(J(d_ 1,d_ 2)\)를 \(\prod_{}\left(j(\alpha_1)-j(\alpha_2)\right)^{\frac{4}{w_1 w_2}}\) 로 정의하자. 여기서 \(\alpha_1, \alpha_2\) 는 각각 $K_1$, $K_2$ 의 ideal class의 representatives
정리 [Gross-Zagier]

\[J (d_ 1,d_ 2)^2=\prod_{\substack{x,n,n'\in \mathbb{Z}, \\ x^2+4nn'=d_ 1d_ 2, \\ n,n'>0}}n^{\epsilon(n')}\]
