Bounded discrepancy conjecture for divisors computing minimal log discrepancies

About 4 years old · traced to

Let dd be a positive integer and let Γ⊂[0,1]\Gamma\subset[0,1] be a DCC set. There exists a positive real number ll, depending only on dd and Γ\Gamma, such that for every lc pair (X∋x,B)(X\ni x,B) of dimension dd, with XX Q\mathbb{Q}-Gorenstein and B∈ΓB\in\Gamma, there is a prime divisor EE over X∋xX\ni x satisfying

a(E,X,B)=mld(X∋x,B)a(E,X,B)={\rm mld}(X\ni x,B)

and

a(E,X,0)≤l.a(E,X,0)\leq l.

Bounded discrepancy conjecture. The divisor computing the minimal log discrepancy can be chosen with discrepancy for (X,0)(X,0) bounded uniformly in terms of dd and Γ\Gamma. The claim is a general conjectural boundedness statement for minimal log discrepancy computations; the supplied excerpt gives no resolution status or further evidence.
