**Professor John Martin**

Department of Mathematics and Statistics

will talk on

*The Alexander Polynomial via the Free Calculus*

**Abstract:**

Knots K_{1} and K_{2} belong to the same knot type if
there is an autohomeomorphism h in R^{3} such that
h(K_{1})=K_{2}. The Alexander polynomial, which is a
polynomial invariant of knot type, will be presented from an algebraic
point of view.
Join us for drinks at the Faculty Club after the talks.

POSTPONED!
