The diagonal form clearly exhibits a symmetry between the positive and negative parts of the spectrum of a "Dirac operator with supersymmetry".

对角化形式清楚表现出“带超对称的狄拉克算子”光谱的正负粒子的对称性。

In Sect. 4.3.4 we show that the Dirac operator in an external field has the same essential spectrum as the free Dirac operator provided the potential vanishes at infinity.

在4.3.4节，我们证明了狄拉克算子在外场中有着对应着无穷远处时零势能极限的自由狄拉克算子的相同的本质谱。
