则H(x,y)是L上虚部为Z值的正定Hermite型。对于偶数n,设Th(n)是C上的θ函数θ的空间,使得对所有L ∈ L,0(w + l)= eTM-′/2 ′/ 0(w).设K是K* 中范数为1的元素的群。若η ∈ K,则在K中存在唯一的积分理想^使得<$与^互质且^~ =(η)。通过以下公式定义Th(n)的自同态:
Then H(x, y) is a positive-definite Hermitian form whose imaginary part is Z-valued on L. For even positive integers n, let Th(n) be the space of theta functions θ on C such that 0(w + /) = eTM-' /2 ' / 0(w) for all / e L . Let K be the group ofnorm one elements in K*. If η e K, there is a unique integral ideal ^ in K such that <$ is relatively prime to ^ and ^~ =(η). Define an endomorphism ^(η) of Th(n) by the formula:
