在 [C13] 這篇論文當中, 考慮秩為 2 的 Drinfeld 模基於 Carlitz 模擴張的 t 模,
Chang 引進了秩為 2 的 Drinfeld 模的第三類週期為此 t 模週期的第二個座標.
在此篇論文中, 我們具體導出了此 t 模的準週期為 Carlitz 模的基本週期, 以及
此 Drinfeld 模的週期, 準週期, 對數, 準對數的代數組合. 接著, 我們利用了
Drinfeld 模的 Legendre 關係以及 Chang-Papanikolas 在 Drinfeld 模週期的
代數獨立性, 我們證明了此 t 模的準週期非零情況下的超越性.
In [C13], Chang introduced periods of the third kind of a rank 2 Drinfeld module as the second coordinate of periods of at-module which is formed by the extension of the Drinfeld module by the Carlitz module. In this thesis, we find the quasi-periods of the t-module explicitly as algebraic combinations of the fundamental period of the Carlitz module, and periods, quasi-periods, logarithms, and quasi-logarithms of the Drinfeld module. Then, using the Legendrerelation for Drinfeld modules and an algebraic independence result of Chang and Papanikolas, we prove the transcendence of quasi-periods of this t-module whenever it is nonzero.
