If you have a question about this talk, please contact Christian Lund.

The starting point of this talk will be a non-glueable categorification of certain tangle invariants generalising the Alexander polynomial of knots and links. After discussing their construction and some properties, 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 why mutation of a (-2,3)-pretzel tangle does not change delta-graded knot Floer homology. This is joint work with Jake Rasmussen.
