Abstract

In this paper, we investigate properties of potential triples (X,Δ,D)(X,\Delta,D) which consists of a pair (X,Δ)(X,\Delta) and a pseudoeffective R\mathbb{R}-Cartier divisor DD. In particular, we show that if DD admits a birational Zariski decomposition, then one can associate a generalized pair structure to the potential triple (X,Δ,D)(X,\Delta,D). Moreover, we can run the generalized MMP on (KX+Δ+D)(K_X+\Delta+D) as special cases. As an application, we also show that for a pklt pair (X,Δ)(X,\Delta), if (KX+Δ)-(K_X+\Delta) admits a birational Zariski decomposition with NQC\mathrm{NQC} positive part, then there exists a (KX+Δ)-(K_X+\Delta)-minimal model.
