Comments welcome", "categories": [ "math.GT", "math.QA", "math.SG" ], "abstract": "The purpose of this thesis is to define a \"local\" version of Ozsv\\'{a}th and Szab\\'{o}'s Heegaard Floer homology $\\operatorname{\\widehat{HFL}}$ for links in the 3-dimensional sphere, i.e. a Heegaard Floer homology $\\operatorname{\\widehat{HFT}}$ for tangles in the closed 3-ball. After studying basic properties of $\\operatorname{\\widehat{HFT}}$ and its decategorified tangle invariant $\\nabla_T^s$, we prove a glueing theorem in terms of Zarev's bordered sutured Floer homology, which endows $\\operatorname{\\widehat{HFT}}$ with an additional glueing structure. For 4-ended tangles, we repackage this glueing structure into certain curved complexes $\\operatorname{CFT}^\\partial$, which we call peculiar modules. This allows us to easily recover oriented and unoriented skein relations for $\\operatorname{\\widehat{HFL}}$. Our peculiar modules enjoy some symmetry properties, which support a conjecture about $\\delta$-graded mutation invariance of $\\operatorname{\\widehat{HFL}}$. In fact, we show that any two links related by mutation about a $(2,-3)$-pretzel tangle have the same $\\delta$-graded link Floer homology. In the last part of this thesis, we explore the relationship between peculiar modules and twisted complexes in the fully wrapped Fukaya category of the 4-punctured sphere. This thesis is accompanied by two Mathematica packages. The first is a tool for computing the generators of $\\operatorname{\\widehat{HFT}}$ and its decategorified tangle invariant $\\nabla_T^s$. The second allows us to compute Zarev's bordered sutured Floer invariants of any bordered sutured manifold using nice diagrams.", "revisions": [ { "version": "v1", "updated": "2016-10-24T17:01:03.000Z" } ], "analyses": { "keywords": [ "heegaard floer theory", "bordered sutured floer invariants", "heegaard floer homology", "peculiar modules", "decategorified tangle invariant" ], "tags": [ "dissertation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
