The boundary-irreducible aligned meridians conjecture

About 20 years old · traced to

Let (M,W)(M,W) be an admissible pair, where WW is a genus two handlebody with meridian disks α\alpha and β\beta, and suppose that M−WM-W is ∂\partial-irreducible. Boundary-irreducible aligned meridians conjecture. Either at least one of M[α]M[\alpha] and M[β]M[\beta] is both irreducible and ∂\partial-irreducible, or α\alpha and β\beta are aligned in MM. By the proposition cited in the source, this formulation is equivalent to the preceding main conjecture; the source gives no resolution.
