Stipsicz's high surgery conjecture for knots
Let be a knot, and for a rational number let denote the -surgery on . Stipsicz's high surgery conjecture. There is an integer such that for every , the surgered -manifold 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.
