N-Crossing Number of Knots and the Bracket Polynomial by Prof. Colin Adams

Mathematics and Statistics Department Faculty Seminar

Abstract:  An n-crossing of a knot is a crossing with n strands passing straight through it. The n-crossing number of a knot  is the least number of n-crossings  in a projection of the knot. In work with students in the SMALL program, we generalize previous results to find a lower bound on the n-crossing number of a knot in terms of its bracket polynomial. No particular background assumed.
