Jonsson–Mustaţă's weighted weak and strong conjectures for log canonical thresholds
Jonsson–Mustaţă's weighted weak and strong conjectures for log canonical thresholds
Let be a regular algebraic variety over a field of characteristic zero. Let be a graded sequence of ideals on , and let be a nonzero ideal on such that . A valuation computes when
Jonsson–Mustaţă's weighted conjecture. The weak version asserts that there exists a quasi-monomial valuation computing ; the strong version asserts that every valuation computing is quasi-monomial.
These are the weighted variants of Jonsson–Mustaţă's conjectures, with the ideal incorporated into the jumping number. The source does not specify whether the weak or strong version is resolved.
