Abundance for threefolds in positive characteristic when $ν = 2$

Zheng Xu

In this paper, we prove the abundance conjecture for threefolds over a perfect field $k$ of characteristic $p > 3$ in the case of numerical dimension equals to $2$ . More precisely,…

Note on the 3-dimensional log canonical abundance in characteristic $> 3$

Zheng Xu

In this paper, we prove the non-vanishing and some special cases of the abundance for log canonical threefold pairs over an algebraically closed field $k$ of characteristic $p > 3$ …
