In noncommutative scalar field theories, the appearing of nonplanar diagrams is related to permutation symmetry of field functions in the interaction Lagrangian, while in NCQED we can not arbitrarily change the positions of field functions in the interaction Lagrangian because different positions of the field functions correspond to different representations of the gauge group.
这里需要特别指出的是NCQED的非平面图产生的原因与非对易标量场根本不同，非对易标量场非平面图的产生是和相互作用拉氏量密度中场函数间位置的置换对称性有关，而在NCQED中我们不能随便交换相互作用拉氏量密度中场函数的位置，因为场函数的不同位置对应着规范群的不同表示。

European Space Agency：欧洲空间局
未来的卫星,例如欧洲空间局(European Space Agency)计划在明年发射的普朗克(Planck)卫星,将为暴涨理论寻找更加确凿的证据. 初看起来,任何成分的能量密度似乎都不可能保持不变,因为空间的膨胀会稀释这种成分. 但一种被称为标量场(scalar field)的特殊能量来源可以避免这种稀释.
