The Azumaya-positive knot conjecture for L-space knots
The Azumaya-positive knot conjecture for L-space knots
Let be a fibered hyperbolic knot whose canonical component is Azumaya positive, meaning that the canonical component satisfies the paper's Azumaya-positivity condition. An -space knot is a knot in admitting a positive Dehn surgery yielding an -space, where an -space is a rational homology -sphere whose Heegaard--Floer homology has rank .
Azumaya-positive knot conjecture. is not an -space knot.
The conjecture is motivated by examples of Azumaya-positive fibered hyperbolic knots whose Alexander polynomials have coefficients other than and , whereas -space knots have symmetrized Alexander polynomials with all nonzero coefficients equal to . The claim remains open in the supplied source.
