紧化Néron型Jacobian

Compactified Jacobians of Néron type

Lucia Caporaso

摘要:

刻画了紧致度- $d$ Jacobian为Néron型的稳定曲线$X$.这意味着:对于$X$的任何一个单参数正则光滑,一般纤维的雅可比矩阵的Néron模型的特殊纤维同构于度- $d$紧化雅可比矩阵的稠密开子集。众所周知,紧化的Néron型Jacobian具有最好的模性质,并且它们被赋予了一个对应用有用的映射性质。

英文摘要:

We characterize stable curves $X$ whose compactified degree-$d$ Jacobian is of Néron type. This means the following: for any one-parameter regular smoothing of $X$, the special fiber of the Néron model of the Jacobian of the generic fiber is isomorphic to a dense open subset of the degree-$d$ compactified Jacobian. It is well known that compactified Jacobians of Néron type have the best modular properties, and that they are endowed with a mapping property useful for applications.
