Lens space surgeries and L-space homology spheres
We describe necessary and sufficient conditions for a knot in an L-space to have an L-space homology sphere surgery. We use these conditions to reformulate a conjecture of Berge about which knots in S admit lens space surgeries.
متن کاملLegendrian Surgeries on Stabilized Legendrian Links
We use Seiberg-Witten monopoles and Ozsváth-Szabó invariants to distinguish between tight contact structures obtained by Legendrian surgeries on stabilized Legendrian links in tight contact 3-manifolds.
متن کاملMontesinos knots, Hopf plumbings and L-space surgeries
Using Hirasawa-Murasugi’s classification of fibered Montesinos knots we classify the L-space Montesinos knots, providing further evidence towards a conjecture of Lidman-Moore that L-space knots have no essential Conway spheres. In the process, we classify the fibered Montesinos knots whose open books support the tight contact structure on S. We also construct L-space knots with arbitrarily larg...
متن کاملThe Renormalized Euler Characteristic and L-space Surgeries
Using the equivalence between the renormalized Euler characteristic of Ozsváth and Szabó, and the Turaev torsion normalized by the Casson-Walker invariant, we make calculations for S p/q(K). An alternative proof of a theorem by Ozsváth and Szabó on L-space surgery obstructions is provided.
متن کاملLinks with No Exceptional Surgeries
We show that if a knot admits a prime, twist-reduced diagram with at least 4 twist regions and at least 6 crossings per twist region, then every non-trivial Dehn filling of that knot is hyperbolike. A similar statement holds for links. We prove this using two arguments, one geometric and one combinatorial. The combinatorial argument further implies that every link with at least 2 twist regions ...
