On the log minimal model program for threefolds over imperfect fields of characteristic p> 5 p>5

O Das, J Waldron - Journal of the London Mathematical Society, 2022 - Wiley Online Library
We prove that many of the results of the log minimal model program hold for threefolds over
fields of characteristic p> 5 p>5 which are not necessarily perfect. This includes the …

On the log minimal model program for -folds over imperfect fields of characteristic

O Das, J Waldron - arXiv preprint arXiv:1911.04394, 2019 - arxiv.org
We prove that many of the results of the LMMP hold for $3 $-folds over fields of characteristic
$ p> 5$ which are not necessarily perfect. In particular, the existence of flips, the cone …

Elementary contractions of algebraic 3-folds

Y Kawamata - Annals of Mathematics, 1984 - JSTOR
The purpose of this paper is to give the first step toward the theory of minimal models of
algebraic 3-folds. Let X be a non-singular projective 3-fold defined over the complex number …

On the canonical bundle formula and log abundance in positive characteristic

J Witaszek - Mathematische Annalen, 2021 - Springer
We show that a weak version of the canonical bundle formula holds for fibrations of relative
dimension one. We provide various applications thereof, for instance, using the recent result …

[引用][C] The number of the minimal models for a 3-fold of general type is finite

Y Kawamata, K Matsuki - Mathematische Annalen, 1987 - Springer
The purpose of this note is to prove the following theorem which shows that" the hope"
stated in [5] actually holds, ie, any 3-fold of general type has at most a finite number of …

[引用][C] Abundance theorem for minimal threefolds

Y Kawamata - Inventiones mathematicae, 1992 - Springer
The purpose of this paper is to finish the proof of the abundance conjecture [K4, Conjecture

The singularities of the parameter surface of a minimal elliptic threefold

A Grassi - arXiv preprint alg-geom/9202025, 1992 - arxiv.org
Let f: X-> S be any elliptic fibration. If X has dimension 3 and is not uniruled, then X has a
minimal model (with terminal singularities)[Mori]. In earlier work we have shown that there …
