摘要：
本文研究了Carlitz模的基本周期$\tildeπ$。主要定理指出，Carlitz周期及其所有超导数在基域$\mathbb{F}_q(θ)$上是代数独立的。我们的方法还揭示了这些超导数与张量幂Carlitz模的周期晶格生成元坐标之间的联系，该联系已在M.Papanikolas未发表的论文中被观察到。具体而言，这些坐标可以通过显式多项式表达式在$\tildeπ$及其超导数中获得。Papanikolas还给出了这些表达式的多种表示形式，我们在此也进行了证明。
英文摘要：
This paper deals with the fundamental period $\tildeπ$ of the Carlitz module. The main theorem states that the Carlitz period and all its hyperderivatives are algebraically independent over the base field $\mathbb{F}_q(θ)$. Our approach also reveals a connection of these hyperderivatives with the coordinates of a period lattice generator of the tensor powers of the Carlitz module which was already observed by M. Papanikolas in a yet unpublished paper. Namely, these coordinates can be obtained by explicit polynomial expressions in $\tildeπ$ and its hyperderivatives. Papanikolas also gave various presentations of these expressions which we also prove here.
