Existence and boundedness of n-complements
Existence and boundedness of n-complements
Let be a pair as in the cited theorems, with special fibre , and let be an Alexeev pair of index when applicable. The condition that has wFt means that it has weakly finite type in the sense used in the paper.
Existence and boundedness of -complements conjecture. The cited theorems should hold without assuming that has wFt. The connectedness assumption on may instead be replaced by a bound on the number of connected components of . The same is expected for Alexeev pairs of index .
The conjecture is stated as an extension of the paper's existence and boundedness results for complements. It is open in the generality asserted here; the source notes that the conjecture holds in dimension at most .
