소개 및 안내사항Content | Title: Convex geometry in algebraic geometry 1부 Abstract : MMP using the convex cone. I will explain how the convex cone of curves is used to run the minimal model program. 2부 Abstract : Positivity using the convex polytope. An Okounkov body is a convex set in the Euclidean space associated to a divisor and it is predicted that those bodies capture many of the positivity of divisors. It is still mysterious and not fully known how the positivity of divisors are encoded in the Okounkov bodies. In this talk, I will explain how to recover some of the positivity of pseudoeffective divisors from Okounkov bodies. |
