DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VCAS/143/">L
 inkage in codimension three</a>\nby Xianglong Ni (University of California
 \, Berkeley\, United StatesUniversity of California\, Berkeley\, CA\, USA)
  as part of IIT Bombay Virtual Commutative Algebra Seminar\n\n\nAbstract\n
 All perfect ideals of codimension two are in the linkage class of a comple
 te intersection (licci)\, but in codimension three and beyond this is no l
 onger the case. I will share some ongoing work\, joint with Lorenzo Guerri
 eri and Jerzy Weyman\, which illustrates how the theory of "higher structu
 re maps" originating from Weyman's generic ring may be used to distinguish
  licci ideals within the broader class of perfect ideals of codimension th
 ree.\n
