摘要:

在这项工作中,我们考虑构造亏格三曲线$X$,使$\mathrm{End}(\mathrm{Jac} (X))\otimes Q$包含全实立方数域$Q(ζ_7 +\barζ_7 )$。我们构造显式三维家庭的泛型成员是一个非超椭圆亏格3曲线与此属性。当$X$是超椭圆曲线时,Hoffman和Wang在以前的工作中进行了研究,Hoffman,Z.梁酒井和王。

英文摘要:

In this work we consider constructions of genus three curves $X$ such that $\mathrm{End}(\mathrm{Jac} (X))\otimes Q$ contains the totally real cubic number field $Q(ζ_7 +\barζ_7 )$. We construct explicit three-dimensional families whose generic member is a nonhyperelliptic genus 3 curve with this property. The case when $X$ is hyperelliptic was studied in a previous work by Hoffman and Wang and some nonhyperelliptic curves were constructed in a previous paper by Hoffman, Z. Liang. Sakai and Wang.
