Anticanonical divisor with good asymptotic base loci

Sung Rak Choi, Sungwook Jang, Dae-Won Lee

In this paper, we give a characterization of Fano type varieties in terms of the asymptotic base loci of $- (K_{X} + Δ)$ . We also show that for a potentially lc pair $(X, Δ)$ , if no plc…

Anticanonical minimal models and Zariski decomposition

Sungwook Jang

Birkar and Hu showed that if a pair $(X, Δ)$ is lc and $K_{X} + Δ$ admits a birational Zariski decomposition, then $(X, Δ)$ has a minimal model. Analogously, we prove that if a pair $(…
