We study the inverse problem in the difference Galois theory of linear differential equations over the difference-differential field with derivation and endomorphism . Our main result is that every linear algebraic group, considered as a difference algebraic group, occurs as the difference Galois group of some linear differential equation over .

代数群作为线性微分方程的差分伽罗瓦群
我们研究了差分-微分域上线性微分方程的差分伽罗瓦理论中的反问题 与推导 和内同态 . 我们的主要结果是每个线性代数群,被认为是一个差分代数群,作为一些线性微分方程的差分伽罗瓦群出现.
