The classification conjecture for irreducible subfactor planar algebras of index between 5 and 3+53+\sqrt{5}

About 13 years old · traced to

Let a subfactor planar algebra mean the planar algebra associated with a finite-index subfactor, and let A∞A_\infty denote the infinite-depth principal graph. Consider irreducible subfactor planar algebras whose index lies in the interval (5,3+5)(5,3+\sqrt{5}). Classification conjecture. The only two irreducible subfactor planar algebras, apart from those with principal graph A∞A_\infty, are the two quantum group subfactors described above, arising from the 3-dimensional representations of SU(2)SU(2) and SU(3)SU(3) at a 14th root of unity. Computer evidence suggests that there are no other finite-depth subfactors in this interval, but a complete classification remains open; the two stated examples are known to be unique for their principal graphs.
