Derksen-Hadas-Makar-Limanov定理(2001)指出多项式环上的加法群的非平凡作用的不变量没有入侵者。本文将这一定理推广到稳定不变量的情形。我们还证明了一个类似的结果,局部有限高导常数。
The Derksen–Hadas–Makar-Limanov theorem (2001) says that the invariants for nontrivial actions of the additive group on a polynomial ring have no intruder. In this paper, we generalize this theorem to the case of stable invariants. We also prove a similar result for constants of locally finite higher derivations.
