考虑域K上的1属曲线的三种显式形式之一:P1的双重覆盖,平面三次或空间四次。对于每一种形式,由经典不变理论给出了曲线的Weierstrass形式的雅可比矩阵及其在无穷远处由k有理除数导出的雅可比矩阵的覆盖映射。我们对这三种情况作了统一的解释。
Abstract Consider a curve of genus one over a field K in one of three explicit forms: a double cover of P1, a plane cubic, or a space quartic. For each form, a certain syzygy from classical invariant theory gives the curve's jacobian in Weierstrass form and the covering map to its jacobian induced by the K-rational divisor at infinity. We give a unified account of all three cases.
