摘要翻译:
本文的目的是提出一种改进的ML不变量(GML),该不变量应考虑射影基上的规则,并允许光滑仿射有理曲面的进一步分层。我们给出了一个非平凡的例子,其中对于不允许C-动作的光滑仿射有理曲面计算GML不变量。我们将GML不变量应用于某些三重条件下的ML不变量的计算。

英文摘要:
The goal of this paper is to present a modified version (GML) of ML invariant which should take into account rulings over a projective base and allow further stratification of smooth affine rational surfaces. We provide a non-trivial example where GML invariant is computed for a smooth affine rational surface admitting no C-actions. We apply GML invariant to computation of ML invariant of some threefolds.
