摘要翻译：
在他关于重数的对数凹性的工作中，Okounkov顺便指出，人们可以把凸体与射影簇上的线性级数联系起来，然后用凸几何来研究这样的线性系统。尽管Okounkov基本上是在大量线束的经典设置中工作的，但事实证明，构造过程是针对任意的大除数进行的。此外，这一观点使关于线性级数渐近不变量的许多基本事实变得透明，并为许多推广打开了大门。本文的目的是对该理论进行系统的发展，并给出一些应用和实例。

英文摘要：
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 opens the door to a number of extensions. The purpose of this paper is to initiate a systematic development of the theory, and to give a number of applications and examples.
