狄拉克共振作为非自伴本征值
Dirac resonances as non-self-adjoint eigenvalues
AI总结:
该研究将三维狄拉克算子的共振定义为预解式亚纯延拓的极点,证明共振集的一个区域可通过畸变狄拉克算子的离散谱刻画且重数不变,并应用该结论在时间反演对称性下证明了克莱默简并性。
AI中文摘要:
我们研究三维狄拉克算子(不一定是自伴的)的共振,将其定义为预解式亚纯延拓的极点。我们证明共振集的一个区域可通过畸变狄拉克算子的离散谱刻画,且重数保持不变。作为应用,我们在时间反演对称性下证明了克莱默简并性。
英文摘要:
We consider resonances of (not necessarily self-adjoint) three-dimensional Dirac operators, defined as poles of the meromorphic continuation of the resolvent. We prove that a region of the resonance set can be characterized by the discrete spectrum of distorted Dirac operators, with preservation of multiplicities. As an application, we prove Kramer's degeneracy under time-reversal symmetry.
