Multiple Aharonov--Bohm eigenvalues: the case of the first eigenvalue on the disk

Analysis of PDEs 2018-03-06 v2

Abstract

It is known that the first eigenvalue for Aharonov--Bohm operators with half-integer circulation in the unit disk is double if the potential's pole is located at the origin. We prove that in fact it is simple as the pole a0a\neq 0.
