Finite-generation conjecture for log canonical rings in Fujiki's class

About 13 years old · traced to

Let XX be a normal complex analytic variety in Fujiki's class C\mathcal C and let Δ\Delta be an effective Q\mathbb Q-divisor on XX such that (X,Δ)(X,\Delta) is log canonical. Its log canonical ring is

R(X,Δ)=⨁m≥0H0(X,OX(⌊m(KX+Δ)⌋)).R(X,\Delta)=\bigoplus_{m\geq 0}H^0(X,\mathcal O_X(\lfloor m(K_X+\Delta)\rfloor)).

Fujiki-class finite-generation conjecture. The ring R(X,Δ)R(X,\Delta) is a finitely generated C\mathbb C-algebra. The source states that this conjecture is equivalent, after taking a resolution, to the preceding compact Kähler formulation and remains open even in the projective case.
