Intersection-dimension conjecture ID-1

From papers

Let (A,n)(A,\mathfrak{n}) be a quasi-unmixed local ring with prime ideals PP and QQ such that P+Q=n\sqrt{P+Q}=\mathfrak{n}. ID-1 conjecture. If

e(A)=e(AP)e(A)=e(A_P)

and A/PA/P is analytically unramified, then

dim(A/P)+dim(A/Q)dim(A).\operatorname{dim}(A/P)+\operatorname{dim}(A/Q)\leq\operatorname{dim}(A).

This is presented as a conjectural generalization of Serre's Intersection Theorem, alongside the symbolic-power conjectures. The supplied context states a theorem proving the analogous inequality under a stronger multiplicity condition, but does not resolve ID-1.
