Stipsicz's high surgery conjecture for knots

At least 4 years old · documented by

Let K⊂S3K\subset S^3 be a knot, and for a rational number rr let Sr3(K)S^3_r(K) denote the rr-surgery on KK. Stipsicz's high surgery conjecture. There is an integer nKn_K such that for every r≥nKr\geq n_K, the surgered 33-manifold Sr3(K)S^3_r(K) admits a tight contact structure. The conjecture is weaker than the question of whether sufficiently large surgeries admit Stein fillable contact structures. It is known for some knots, while the paper presents it as unresolved in the generality stated.
