一、中文摘要 國科會自八十七年度起補助專題計畫 成果報告準備方式有所變革,本文提供一 個統一格式,可供主持人撰寫報告時參考 使用。 Abstract

This is the first-year progress report of my research project "Rationality problem and Galois theorey (1/3)". What we have finished are

(1) to study the invariants of Weyl algebras ; see:

Generation of invariants, J. Algebra 221 (1999) 232~241。

(2) to study the rationality problem of a projective linear automorphism ; see:

Rationality of some projective linear

actions, J. Algebra 228 (2000)

643~658。

(3) to study the history and the recent progress of Tsen's Theorem ; see:

Chiungtze C. Tsen (1898~1940) and Tsen's theorems, Rocky Mountain J. of Mathematics 29 (2000) 1237~1269。 二、本年進度 本計劃為三年期計劃的第一年。在過去 一年中,我們完成以下工作: (1) 研究 Weyl algebras 的不變量,發表 在:

Generation of invariants, J. Algebra 221 (1999) 232~241。

(2) 研究射影平面的有理性問題,發表 在

Rationality of some projective linear

actions, J. Algebra 228 (2000)

643~658。

(3) 研究 Tsen's Theorem 的歷史及其最 近發展,發表在

Chiungtze C. Tsen (1898~1940) and Tsen's theorems, Rocky Mountain J.

of Mathematics 29 (2000)

另外因為 Gal(L/F ) 是 Gal(L/K) 的 normal subgroup, 所以由 Second Fundamental Theorem 4.1.8 知 F/K 也是 Galois extension, 而且 Gal(F/K) isomorphic to Gal(L/K)/Gal(L/F )
