摘要翻译:
我们考虑了具有有理雅可比系数的周环。假定D是曲线的无基点G^R_d中的一个因子,使得正则因子K是因子D的倍数,我们找到了重言圈之间的关系。我们给出了在p^1上具有d次复盖且分支点均为d阶的曲线的应用,进而给出了超椭圆曲线的应用。

英文摘要:
We consider the Chow ring with rational coefficients of the Jacobian of a curve. Assume D is a divisor in a base point free g^r_d of the curve such that the canonical divisor K is a multiple of the divisor D. We find relations between tautological cycles. We give applications for curves having a degree d covering of P^1 whose ramification points are all of order d, and then for hyperelliptic curves.
