从这个角度来看,cpL(X) 的方程只是 theta 函数之间的关系。对于例如模问题的应用,人们希望这些关系的系数是由 L 在 V 中的 0 点处确定的某些 theta 函数的值。传统上,此类方程称为 theta 关系。首先,例子是黎曼 theta 关系。这些是某些二次方程,对于 L = M" 有效,其中 n ^ 4 为偶数,并且 X 上有一些充足的线 b ndle M。除了少数例外,所有 theta 关系都可以从黎曼恒等式中推导出来(参见 [M 3],第 211 页)。一个明显的例外是椭圆曲线的平面三次方程。
From this point of view equations for cpL(X) are just relations among the theta functions. For applications for example on moduli problems one would like to have, that the coefficients of these relations are values of certain theta functions determined by L at the point 0 in V. Classically such equations are called theta relations. Examples are, first of all, Riemann's theta relations. These are certain quadratic equations, valid for L = M", with n ^ 4 even and some ample line b ndle M on X. With only a few exceptions, all theta relations can be deduced from the identities of Riemann (see [M 3], p. 211). An obvious exception is the plane cubic equation for an elliptic curve.
