Let (X,D= P ... consisting of a normal algebraic variety Xand a boundary Don Xa log variety or a log pair. Here a boundary is a Q-Weil divisor D= P diDi such that 0 ≤di≤1 for all i. A contraction is a projective morphism ϕ: X→Zof normal varieties Webstandard boundary coefficients. We now state Shokurov’s conjectures on the boundedness of complements. real number and d a natural number. Then, there exist a finite set N δ,d,Γ of positive integers and ε > 0 such that any d-dimensional totally δ-lc weak log Fano pair (X/P ∈ Z,B), where B ∈ Γ, is (ε,n)-complementary/P ∈ Z for ...

Webequivalence and the sum of coefficients of the boundary. We describe such varieties for which the equality holds and show that all of them are toric. 1. Introduction. The aim of this note is to discuss the birational characterization of toric varieties. Let X be a normal projective toric variety and letD = r i=1 Di be the sum of invariant ... Web592 V. V. SHOKUROV X has canonical (respectively terminal) singularities if all the a, are nonnegative (respec-tively positive). We remark that from the point of view of linear systems the routine singularities should perhaps be called canonical, and canonical singularities pluricanoni-cal.
