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…

On canonical bundle formula for fibrations of curves with arithmetic genus one

Jingshan Chen, Chongning Wang, Lei Zhang

In this paper, we develop canonical bundle formulas for fibrations of relative dimension one in characteristic $p > 0$ . For such a fibration from a log pair $f : (X, Δ) \to S$ , i…

Gorenstein stable log surfaces with $(K_{X} + Λ)^{2} = p_{g} (X, Λ) - 1$

Jingshan Chen

In this paper, we will give a complete classification of Gorenstein stable log surfaces $(X, Λ)$ with $(K_{X} + Λ)^{2} = p_{g} (X, Λ) - 1$ , where $p_{g} (X, Λ) := h^{0} (X, K_{X} + Λ)$ . In particular, we class…
