Precise inversion of adjunction conjecture for minimal log discrepancies

About 5 years old · traced to

Let (X,a)(X,\mathfrak{a}) be a log pair, let DD be a normal Cartier prime divisor, and let x∈Dx\in D be a closed point. Suppose that DD is not contained in the cosupport of the R\mathbb{R}-ideal sheaf a\mathfrak{a}. PIA conjecture. One has

mld⁡x(X,aOX(−D))=mld⁡x(D,aOD).\operatorname{mld}_x\bigl(X,\mathfrak{a}\mathcal{O}_X(-D)\bigr)=\operatorname{mld}_x\bigl(D,\mathfrak{a}\mathcal{O}_D\bigr).

This is the precise inversion of adjunction statement studied in the paper; the supplied text does not establish its general resolution status.
