We determine a counterexample to strong diamagnetism for the Laplace operator in the unit disc with a uniform magnetic field and Robin boundary condition. The example follows from the accurate asymptotics of the lowest eigenvalue when the Robin parameter tends to − ∞ $-\infty $ .

磁性罗宾拉普拉斯算子强抗磁性的反例

我们确定了具有均匀磁场和罗宾边界条件的单位圆盘中拉普拉斯算子的强抗磁性反例。该示例遵循当 Robin 参数趋向于 − ∞ $-\infty $ 时最低特征值的精确渐近线。
