Syzygies of the secant variety of a curve

Jessica Sidman, Peter Vermeire

Published 2008-06-18, updated 2009-02-26Version 3

We show that the secant variety of a linearly normal smooth curve of degree at least 2g+3 is arithmetically Cohen-Macaulay, and we use this information to study the graded Betti numbers of the secant variety.
