Abstract

In this paper, we show that along Q\mathbb Q-Fano fibration, when general fibres, base and central fiber (with at worst Kawamata log terminal singularities)are K-poly stable then there exists a relative K\"ahler-Einstein metric. We introduce the fiberwise K\"ahler-Einstein foliation and we mention that the main difficulty to obtain higher estimates is to solve relative CMA equation along such foliation. We propose a program such that for finding a pair of canonical metric (ωX,ωB)(\omega_X,\omega_B), which satisfies in Ric(ωX)=πωB+π(ωWP)+[N]Ric(\omega_X)=\pi^*\omega_B+\pi^*(\omega_{WP})+[\mathcal N] on K-poly stable degeneration π:XB\pi:X\to B, where Ric(ωB)=ωBRic(\omega_B)=\omega_B, we need to have Canonical bundle formula.
