局部幂零模导子与Hilbert第十四问题

Locally nilpotent module derivations and the fourteenth problem of Hilbert

Mikiya Tanaka

摘要:

给定特征为零的域$k$上的仿射代数$B$上的局部幂零导子,我们考虑一个允许局部幂零模导子$δ_M$的可生成$B$ -模$M$(见下面的定义1.1).设$A=\Ker δ$和$M_0=\Ker δ_M$。我们询问$M_0$是否是一个可编译生成的$A$模块。一般来说,存在与希尔伯特第十四问题密切相关的反例。我们还寻找了有限生成的一些充分条件。

英文摘要:

Given a locally nilpotent derivation on an affine algebra $B$ over a field $k$ of characteristic zero, we consider a finitely generated $B$-module $M$ which admits a locally nilpotent module derivation $δ_M$ (see Definition 1.1 below). Let $A=\Ker δ$ and $M_0=\Ker δ_M$. We ask if $M_0$ is a finitely generated $A$-module. In general, there exist counterexamples which are closely related to the fourteenth problem of Hilbert. We also look for some sufficient conditions for finite generation.
