摘要翻译:
我们证明了柱面在Koras-Russell三次仿射上的Makar-Limanov不变量是平凡的。这意味着在加法群的所有代数作用下不变的正则函数是常数。

英文摘要:
We show that the Makar-Limanov invariant of the cylinder over the Koras-Russell cubic affine threefold is trivial. This means that regular functions which are invariant under all algebraic actions of the additive group on this variety are constants.
