Analytic termination conjecture for the minimal model program for log canonical pairs

Let π ⁣:XY\pi\colon X\to Y be a projective morphism from a normal analytic variety XX to a Stein space YY, and let WYW\subset Y be a compact subset such that π\pi and WW satisfy (P). Let (X,Δ)(X,\Delta) be a log canonical (lc) pair.

Analytic MMP termination conjecture. After shrinking YY around WW, there exists a finite sequence of steps of a (KX+Δ)(K_X+\Delta)-minimal model program over YY around W,representedbybimeromorphiccontractionsoverW, represented by bimeromorphic contractions over Y,thatterminateswithagoodminimalmodeloraMorifiberspaceover, that terminates with a good minimal model or a Mori fiber space over YaroundaroundW.

This is the complex-analytic analogue of the algebraic termination conjecture for lc pairs and is intended to relate analytic minimal model theory to the projective case. Its resolution is not supplied in the source.
