摘要:

设$C$是数域$M$上光滑的、绝对不可约的亏格- $3$曲线.假设$C$的雅可比矩阵与六次CM-域$K$有复乘。进一步假设$K$不包含虚二次子域。给出了$M$的素数$\mathfrak{p}$的一个界,使得$C$在$\mathfrak{p}$的稳定约化包含亏格$1$的三个不可约分支.

英文摘要:

Let $C$ be a smooth, absolutely irreducible genus-$3$ curve over a number field $M$. Suppose that the Jacobian of $C$ has complex multiplication by a sextic CM-field $K$. Suppose further that $K$ contains no imaginary quadratic subfield. We give a bound on the primes $\mathfrak{p}$ of $M$ such that the stable reduction of $C$ at $\mathfrak{p}$ contains three irreducible components of genus $1$.
