Graduate Organized Seminar - The Quillen-Suslin Theorem

Drew Lewis, Department of Mathematics, Washington University in St. Louis

June 20, 2012 - 4:00 pm to 5:00 pm
Location: Cupples I, Room 6 | Host: Timothy Chumley

Abstract: We will discuss a proof of the Quillen-Suslin theorem, which states that projective modules over a polynomial ring (over a field) are in fact free modules. As a starting point, we will assume Serre's theorem that such modules must be stably free, and use the technique of unimodular rows to derive the Quillen-Suslin result.
