秩为2的Drinfeld模的第三类周期与模的代数独立性

Periods of third kind for rank 2 Drinfeld modules and algebraic independence of logarithms

Chieh-Yu Chang

摘要:

与定义在数域上的椭圆曲线的第三类微分的阿贝尔积分积分的周期类似,我们引入了定义在代数函数域上的秩为2的Drinfeld Fq[t]-模ρ的第三类周期的概念,并给出了它们的显式表达式.当rho与可分扩张作复乘时,证明了rho的CM域上线性无关的代数点的rho代数无关性.结合文献[CP 08]中的主要结果,我们完全确定了奇特征秩为2的Drinfeld Fq[t]-模的第一、第二、第三类周期之间的所有代数关系.

英文摘要:

In analogy with the periods of abelian integrals of differentials of third kind for an elliptic curve defined over a number field, we introduce a notion of periods of third kind for a rank 2 Drinfeld Fq[t]-module rho defined over an algebraic function field and derive explicit formulae for them. When rho has complex multiplication by a separable extension, we prove the algebraic independence of rho-logarithms of algebraic points that are linearly independent over the CM field of rho. Together with the main result in [CP08], we completely determine all the algebraic relations among the periods of first, second and third kinds for rank 2 Drinfeld Fq[t]-modules in odd characteristic.
