论文摘要
我们表征了具有离散频谱的自动接合操作员A的级别驱动b的可能光谱,尤其是证明B的光谱可能包括任意代数多重性的任何数量的实际或非现实特征值
We characterize possible spectra of rank-one perturbations B of a self-adjoint operator A with discrete spectrum and, in particular, prove that the spectrum of B may include any number of real or non-real eigenvalues of arbitrary algebraic multiplicity
