Contact structures and reducible surgeries
Title: | Contact structures and reducible surgeries |
Authors: | Lidman, T Sivek, S |
Item Type: | Journal Article |
Abstract: | We apply results from both contact topology and exceptional surgery theory to study when Legendrian surgery on a knot yields a reducible manifold. As an application, we show that a reducible surgery on a non-cabled positive knot of genus must have slope , leading to a proof of the cabling conjecture for positive knots of genus 2. Our techniques also produce bounds on the maximum Thurston–Bennequin numbers of cables. |
