In his work on log-concavity of multiplicities, Okounkov showed in passing that one could associate a convex body to a linear series on a projective variety, and then use convex geometry to study such linear systems. Although Okounkov was essentially working in the classical setting of ample line bundles, it turns out that the construction goes through for an arbitrary big divisor. Moreover, this viewpoint renders transparent many basic facts about asymptotic invariants of linear series, and…

From Convex Geometry of Certain Valuations to Positivity Aspects in Algebraic Geometry
A few years ago Okounkov associated a convex set (Newton–Okounkov body) to a divisor, encoding the asymptotic vanishing behaviour of all sections of all powers of the divisor along a fixed flag. This
Newton–Okounkov bodies: an approach of function field arithmetic
By using the method of Arakelov geometry in the function field setting, we associate, to each graded linear series which is birational and of sub-finite type, a convex body whose Lebesgue measure
Convex bodies and multiplicities of ideals
We associate convex regions in ℝn to m-primary graded sequences of subspaces, in particular m-primary graded sequences of ideals, in a large class of local algebras (including analytically
Convex bodies and representation theory
The theory of toric varieties connects the combinatorics of convex integral polytopes with the geometry of toric varieties. In the case of a toric variety X , its associated polytope ∆ coincides with
Okounkov bodies of filtered linear series
Abstract We associate to certain filtrations of a graded linear series of a big line bundle a concave function on its Okounkov body, whose law with respect to the Lebesgue measure describes the
Local positivity of linear series on surfaces
We study asymptotic invariants of linear series on surfaces with the help of Newton-Okounkov polygons. Our primary aim is to understand local positivity of line bundles in terms of convex geometry.
Convex bodies associated to actions of reductive groups
We associate convex bodies to a wide class of graded G-algebras where G is a connected reductive group. These convex bodies give information about the Hilbert function as well as multiplicities of
Vanishing sequences and Okounkov bodies
We define and study the vanishing sequence along a real valuation of sections of a line bundle on a normal projective variety. Building on previous work of the first author with Huayi Chen, we prove
Newton-Okounkov Bodies over Discrete Valuation Rings and Linear Systems on Graphs
The theory of Newton-Okounkov bodies attaches a convex body to a line bundle on a variety equipped with flag of subvarieties. This convex body encodes the asymptotic properties of sections of powers


Convex bodies and algebraic equations on affine varieties
Given an affine variety X and a finite dimensional vector space of regular functions L on X, we associate a convex body to (X, L) such that its volume is responsible for the number of solutions of a
The pseudo-effective cone of a compact K\
We prove that a holomorphic line bundle on a projective manifold is pseudo-effective if and only if its degree on any member of a covering family of curves is non-negative. This is a consequence of a
Note on the Cohomology Ring of Spherical Varieties and Volume Polynomial
Let X be a (smooth) projective spherical variety. We give a description of the subalgebra of the cohomology ring H * (X, Q) generated by H 2 (X, Q), in terms of the volume of polytopes. This
The Asymptotic Growth of Equivariant Sections of Positive and Big Line Bundles
If a finite group acts holomorphically on a pair (X,L), where X is a complex projective manifold and L a line bundle on it, for every k the space of holomorphic global section of the k-th power of L
Boundedness of pluricanonical maps of varieties of general type
Using the techniques of [20] and [10], we prove that certain log forms may be lifted from a divisor to the ambient variety. As a consequence of this result, following [22], we show that: For any

Let G be a complex reductive group and X a projective spherical G-variety. Moreover, assume that the subalgebra A of the cohomology ring H^*(X, R) generated by the Chern classes of line bundles has
Szego kernels and finite group actions
In the context of almost complex quantization, a natural generalization of algebro-geometric linear series on a compact symplectic manifold has been proposed. Here we suppose given a compatible
The purpose of the present expository note is to give an invitation to this circle of ideas. Our hope is that this informal overview might serve as a jumping off point for the more technical

Big line bundles over arithmetic varieties
We prove a Hilbert-Samuel type result of arithmetic big line bundles in Arakelov geometry, which is an analogue of a classical theorem of Siu. An application of this result gives equidistribution of
