Weak Brumfiel–Hilden conjecture for the A-polynomial ideal

About 10 years old · traced to

For a knot K⊂S3K\subset S^3, let J⊂C[m±1,l±1]J\subset \mathbb{C}[m^{\pm1},l^{\pm1}] be the kernel of the algebra map determined by the meridian and longitude, and let AK(m,l)A_K(m,l) be the AA-polynomial. Weak Brumfiel–Hilden conjecture. The ideals satisfy

⟨J,m−m−1⟩=⟨AK(m,l),m−m−1⟩.\langle J,m-m^{-1}\rangle=\langle A_K(m,l),m-m^{-1}\rangle.

This is presented as a weaker version of the Brumfiel–Hilden conjecture that J=⟨AK(m,l)⟩J=\langle A_K(m,l)\rangle; the source does not report a resolution, so the weaker equality remains open.
