The instanton L-space surgery conjecture for knots
The instanton L-space surgery conjecture for knots
Let be a knot, let , and suppose that has no -torsion. An instanton L-space is a rational homology sphere satisfying
Instanton L-space surgery conjecture. Under these assumptions, must be an instanton L-space, meaning
and must be an instanton L-space knot. Consequently, is fibered and strongly quasi-positive, and . This conjecture extends the paper's integral-torsion criterion from nonzero integral surgeries to arbitrary nonzero rational surgeries; the stated consequences are supported by the cited results, while the conjectural implication itself remains open.
