Quasimonomial valuation conjecture for controlled-growth subadditive sequences

At least 13 years old · documented by

Let RR be an excellent regular domain of equicharacteristic zero, let b∙\mathfrak b_\bullet be a subadditive sequence of ideals in RR, and say that it has controlled growth when

1jv(bj)≤v(b∙)≤1j(v(bj)+A(v))\frac1jv(\mathfrak b_j)\le v(\mathfrak b_\bullet)\le\frac1j\bigl(v(\mathfrak b_j)+A(v)\bigr)

for every j≥1j\ge1 and every quasimonomial valuation vv on RR. Controlled-growth subadditive valuation conjecture. If there are a maximal ideal m\mathfrak m in RR and a positive integer pp such that mpj⊆bj\mathfrak m^{pj}\subseteq\mathfrak b_j for all jj, then there exists a quasimonomial valuation vv on RR that computes lct⁡(b∙)\operatorname{lct}(\mathfrak b_\bullet).

The source says this conjecture is equivalent to the corresponding graded-sequence conjecture and is known in dimensions one and two. It remains open in higher dimensions.
