### The Thurston polytope for four-stranded pretzel links

Joan Licata

#### Abstract

In this paper we use Heegaard Floer link homology to determine the dual Thurston polytope for pretzel links of the form $P(−2r1−1,2q1,−2q2,2r2+1),ri,qi∈ℤ+$. We apply this result to determine the Thurston norms of spanning surfaces for the individual link components, and we explicitly construct norm-realizing surfaces for the homology classes which are vertices of the Thurston polytope.
