Commutative Algebra and Algebraic Geometry: The Fellowship of the Ring: Liaison among curves in $P^3$
Seminar | October 3 | 5-6 p.m. | 939 Evans Hall

Two curves X and Y are linked if their union is a complete intersection in $P^3$. The equivalence relation generated by linkage is called liaison. We survey the results on free resolution of curves, classification of liaison classes and minimal curves, and mention the relevance to the study of the Hilbert scheme of curves in $P^3$.
