A Bound of the Number of Weighted Blow-ups to Compute the Minimal Log Discrepancy for Smooth 3-Folds
Shihoko Ishii (University of Tokyo)
Abstract
In the talk I will show that the minimal log discrepancy of every pair consisting of a smooth 3-fold and a “general” real ideal is computed by the divisor obtained by at most two weighted blow ups. Our proof suggests the following conjecture: Every pair consisting of a smooth N-fold and a “general” real ideal is computed by a divisor obtained by at most N-1 weighted blow ups. This is regarded as a weighted blow up version of Mustata-Nakamura’s conjecture.
