About what?

In the 1920s, J. W. Alexander discovered the first polynomial invariant for knots. It would take several more decades for topologists to realize the full potential of this construction, which has inspired several similar invariants and now is a cornerstone of modern knot theory. In this talk we will see three different ways of calculating the Alexander polynomial, discuss the connections between them.
