Description: | [DMS Seminar] Subhankar Dey (SUNY Buffalo, NY) -- Cable knots are not thin |

Date: | Wednesday, Jan 15, 2020 |

Time: | 3 p.m. - 4 p.m. |

Venue: | G09, A P C Ray |

Details: | Thurston's geometrization conjecture and its subsequent proof for Haken manifolds distinguish knots in S^3 by the geometries in the complement of the knots. While the definition of alternating knots make use of nice knot diagrams, Knot Floer homology, a knot invariant toolbox, defined by Ozsvath-Szabo and Rasumussen, generalizes the definition of alternating knots in the context of knot Floer homology and defines family of quasi-alternating knots which contains all alternating knots. Using Lipshitz-Ozsvath-Thurston's bordered Floer homology, we prove a partial affirmation of a folklore conjecture in knot Floer theory, which bridges these two viewpoints of looking at knots. |
