This page:31

Abstract: I will explain an interpretation of the Alexander polynomial as a universal invariant of long knots associated to the complex Hopf algebra of regular functions on the affine linear algebraic group of complex invertible upper triangular 2-by-2 matrices of the form
$$ (
\begin{array}{cc} a & b
0 & 1 \end{array}
). $$
