论文摘要
我们证明了经典结果的积极特征类似物，即一个变量中非恒定差分运算符的中央器是可交换的。这导致了通过减少模型$ p。$ $ p。
We prove a positive characteristic analogue of the classical result that the centralizer of a nonconstant differential operator in one variable is commutative. This leads to a new, short proof of that classical characteristic zero result, by reduction modulo $p.$
