Title: Linkage in codimension three
Abstract: All perfect ideals of codimension two are in the linkage
class of a complete intersection (licci), but in codimension three and
beyond this is no longer the case. I will share some ongoing work, joint
with Lorenzo Guerrieri and Jerzy Weyman, which illustrates how the
theory of "higher structure maps" originating from Weyman's generic ring
may be used to distinguish licci ideals within the broader class of
perfect ideals of codimension three.
