For fixed flux parameter $\alpha$, let the pole move in a direction specified by the angle of the vector $a=|a|(\cos\alpha,\sin\alpha)$. Almost-every-direction bifurcation conjectu…

Let $a\mapsto\lambda_a$ be the eigenvalue map for the Aharonov–Bohm operator considered in the paper, and suppose that an extremal point occurs where the eigenvalue is not simple.…
