abstract

In this paper, we give a partial affirmative answer to the BAB conjecture for $3$-folds in characteristic $p>5$. Specifically, we prove that a set $\mathcal{D}$ of weak Fano $3$-folds over an uncountable algebraically closed field is bounded, if each element $X \in \mathcal{D}$ satisfies certain conditions regarding the Gorenstein index, a complement and Kodaira type vanishing. In the course of the proof, we also study a uniform lower bound for Seshadri constants of nef and big invertible sheaves on projective $3$-folds.

    math.AG 2025-01 conditional novelty 6.0 of 10

    The paper establishes a canonical bundle formula for Fano-type threefold fibrations in large characteristic and proves effective birationality for strongly F-regular weak Fano varieties with bounded Gorenstein index.
