DESCRIPTION:The starting point of this talk will be a non-glueable categor
 ification of certain tangle invariants generalising the Alexander polynomi
 al of knots and links. After discussing their construction and some proper
 ties\, we will specialise to 2-stranded tangles and explore what a glueing
  formula should look like in this case. As an application\, we will see wh
 y mutation of a (-2\,3)-pretzel tangle does not change delta-graded knot F
 loer homology. This is joint work with Jake Rasmussen.
