Query: The Gassner representation for string links   The Gassner representation of the pure braid group to $GL_n(Z[Z^n])$ can be
extended to give a representation of the concordance group of $n$-strand string
links to $GL_n(F)$, where $F$ is the field of quotients of $\zz[\zz^n]$, $ F =
Q(t_1,...,t_n)$; this was first observed by Le Dimet. Here we present simple
new perspectives on its definition, its computation, and its applications to
obtain both general results and interesting family of examples.
