Relative Mmp Without Q-Factoriality

Research output: Contribution to journalArticlepeer-review

Abstract

We consider the minimal model program for varieties that are not Q-factorial. We show that, in many cases, its steps are simpler than expected. The main applications are to log terminal singularities, removing the earlier Q-factoriality assumption from several theorems of Hacon-Witaszek and de Fernex-Kollar-Xu.
