The log canonical center realization conjecture for Du Bois subsets

Let (X,Δ)(X, \Delta) be a quasi-projective, log canonical pair of dimension nn. Let VXV\subset X be a closed subset such that

mld(V,X,Δ)<lcg(n)\operatorname{mld}(V, X,\Delta)<\operatorname{lcg}(n)

and suppose that VV contains all log canonical centers of (X,Δ)(X, \Delta). A log canonical pair (X,Θ)(X,\Theta) is a pair with log canonical singularities. The conjecture asks whether there is such a pair for which VV is the union of all log canonical centers of (X,Θ)(X,\Theta).
