Witryna11 cze 2024 · We introduce four invariants of algebraic varieties over imperfect fields, each of which measures either geometric non-normality or geometric non-reducedness. The first objective of this article is to establish fundamental properties of these invariants. We then apply our results to curves over imperfect fields.

Witryna15 sie 2015 · 9. Over an algebraically closed field k of characteristic 0, the functor that sends a finite k -group scheme to its group of k -points is an equivalence of categories from the category of finite k -group schemes to the category of finite groups. In characteristic p, the story is more involved because there are non-smooth k -group … WitrynaDOI: 10.1016/0168-1176(94)04099-S Corpus ID: 94999326; Ion separation in imperfect fields on the quadrupole mass analyser Part V.
