Computing Alexander polynomials for arborescent links

Geometric Topology 2026-04-02 v1

Abstract

For arborescent links, we present an efficient method of computing their Alexander polynomials. Applying this method, we express the Alexander polynomials of Montesinos links in terms of certain functions associated to rational tangles which can be computed recursively. Specifically, we deduce explicit closed formulas for all pretzel links.
