ALEXANDER–LIN TWISTED POLYNOMIALS
2011
Journal of knot theory and its ramifications
X.S. Lin's definition of twisted Alexander knot polynomial is extended for finitely presented groups. J. Cha's fibering obstruction theorem is generalized. The group of the 2-twist-spun trefoil knot is seen to have a faithful representation that yields a trivial twisted Alexander polynomial.
