The Betti table of a high degree curve is asymptotically pure

Algebraic Geometry 2014-01-09 v2

Abstract

We prove that asymptotically in the degree, the main term of the Boij--S\"oderberg decomposition of a high degree curve is a single pure diagram that only depends on the genus of the curve. This answers a question of Ein and Lazarsfeld in the case of curves.
