THIS LECTURE HAS BEEN POSTPONED TILL JANUARY 2The Weizmann Institute of Science Faculty of Mathematics and Computer Science Algebraic Geometry and Representation Theory Seminar Note that there is another talk on Tuesday the same week! Leonid Makar-Limanov Wayne State University will speak on A new proof of the AMS theorem (that is Abhyankar-Moh-Suzuki) and related open problems ((Previously scheduled for Wednesday, December 26, 2012 at 11:00))THIS LECTURE HAS BEEN POSTPONED TILL JANUARY 2Abstract: One of the most famous theorems on polynomials in one variable is the following statement: if two polynomials $f$ and $g$ from $K[z]$, where $K$ is a field, generate all $K[z]$ then either the degree of $f$ divides the degree of $g$ or the degree of $g$ divides the degree of $f$ (if the characteristic of $K$ is finite additional restrictions are necessary). There are about dozen published proofs of this fact, some of them wrong, and I'll discuss a new proof, and some related open problems. --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: Yaeli Malka <yaeli.malka@weizmann.ac.il>
