假设可观测量的局部性和能量的正性，表明能量动量算子的联合谱在所有超选择扇区中具有洛伦兹不变的下边界。如果洛伦兹对称性（自发地）破缺，例如在量子电动力学的带电扇区中，这个结果就很有趣。
Assuming locality of the observables and positivity of the energy it is shown that the joint spectrum of the energy-momentum operators has a Lorentz-invariant lower boundary in all superselection sectors. This result is of interest if the Lorentz-symmetry is (spontaneously) broken, such as in the charged sectors of quantum electrodynamics.
