Geometric singularities of regular surfaces with nef anti-canonical divisors over imperfect fields

Chongning Wang, Lei Zhang

Let $S$ be a regular projective surface over a field $k$ of characteristic $p > 0$ , with $H^{0} (S, O_{S}) = k$ and $- K_{S}$ nef. We prove that $S$ is geometrically integral over $k$ …

Irregular threefolds with numerically trivial canonical divisor

Jingshan Chen, Chongning Wang, Lei Zhang

In this paper, we classify irregular threefolds with numerically trivial canonical divisors in positive characteristic. For such a variety, if its Albanese dimension is not maximal…
