Abstract

Given an algebraic set, i.e., the solution set of a family of polynomial equations, what is the minimal number of polynomials needed to define this set?  The question is surprisingly difficult, with a rich history.  We will give a partial survey, and discuss results and questions coming from local cohomology theory.
