Query: A polynomial invariant for plane curve complements: Krammer polynomials   We use the Krammer representation of the braid group in Libgober's invariant
and construct a new multivariate polynomial invariant for curve complements:
Krammer polynomial. We show that the Krammer polynomial of an essential braid
is equal to zero. We also compute the Krammer polynomials of some certain
n-gonal curves.
