We prove an equivalence between the category underlying combinatorial tangle Floer homology and the contact category by building on the prior work of Lipshitz, Ozsváth, and Thurston and later Zhan. In his 2015 paper "Formal Contact Categories", Cooper establishes a relationship between the categories associated to oriented surfaces by Heegaard Floer theory and embedded contact theory. In this thesis, we examine a special case of his general argument to show an equivalence between the categories discussed by Petkova and Vértesi and those discussed by Tian. To do this, we construct two bimodules associated to the transformations between the underlying structure of combinatorial tangle Floer homology and the contact category. We take the tensor product of these bimodules and show that the product is equivalent to the identity, inducing an isomorphism between the categories of interest.

- Public Abstract (ETD)
This thesis relates two subfields of topology - tangle Floer homology and contact theory. Tangle Floer homology quantifies properties of pieces of knots called tangles, while contact theory allows topologists to think about structures so twisted that a surface cannot follow them. We exploit that both theories, at the root, use bordered Heegaard Floer homology. This allows us to show that the two theories have equivalent underlying structure and are thus related. The bulk of this thesis is proving that equivalence.
