Torsion closures of ideals (25min)

Abstract: The torsion closure of an ideal in a polynomial ring is a construction for identifying the solutions of a system of polynomial equations in roots of unity. Being able to compute torsion closures has potential applications in many branches of mathematics. I'll discuss an ongoing project to use libsingular to compute torsion closures, and an intended application to a problem in Euclidean geometry.
