Cylindricity of weighted singular del Pezzo surfaces over fields of characteristic zero

In-Kyun Kim, Dae-Won Lee, Masatomo Sawahara

In this paper, we study the cylindricity of -forms of singular del Pezzo surfaces obtained by blowing up weighted projective planes over an arbitrary fie…

On the quasi-monomiality of the - and -invariants

Donghyeon Kim, Dae-Won Lee

In this paper, we show that for any projective klt pair over an algebraically closed field of characteristic \(0\) and any big -Cartier -divisor $L…

Structure of the Anticanonical Minimal Model Program for Potentially klt Pairs

Donghyeon Kim, Dae-Won Lee

We give an alternative proof of the existence of the anticanonical minimal model program for potentially klt pairs, assuming the anticanonical divisor admits a birational Zariski d…

Minimal model program on the generic fiber of log Calabi-Yau type fibration

Donghyeon Kim, Dae-Won Lee

We study the minimal model program on the geometric generic fiber of a fibration such that for a Zariski dense subset , is an -lc log C…

A valuative approach to the anticanonical minimal model program

Sung Rak Choi, Sungwook Jang, Donghyeon Kim +1

In this paper, we show that the log canonical threshold of a potentially klt triple can be computed by a quasi-monomial valuation. The notion of potential triples provides a larger…

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 . We also show that for a potentially lc pair , if no pl…
