在這篇論文中,我們回顧海斯[1]關於德林費爾德模的理論並藉由符號正規化德林費爾德模的直和構造出一個希爾伯特-布魯蒙索t-模的簡單例子rho^K。我們用t-動機去描述透過「理想作用」在rho^K得到的同源,並且提供一個例子說明理想作用在rho^K的同構類並不會有簡單可遞性。
In this thesis, we review Hayes' theory [1] of Drinfeld modules and construct a simple case of Hilbert-Blumenthal $t$-module rho^K by the direct sum of sgn-normalized Drinfeld modules. We use the language of $t$-motives to describe the general notion of the isogenies of rho^K coming from ``ideal actions" and give an example to show that the ideal action on the isomorphism classes of rho^K may not be simply transitive.
