Starting with a simple two-scalar field system coupled to a modified measure that is independent of the metric, we, first, find a Born–Infeld dynamics sector of the theory for a scalar field and second, show that the initial scale invariance of the action is dynamically broken and leads to a scale charge nonconservation, although there is still a conserved dilatation current.

一个 Born-Infeld 标量和一个动态违反来自修改的测量动作的尺度不变性

从一个简单的双标量场系统开始，该系统耦合到一个与度量无关的修改度量，我们首先找到了标量场理论的 Born-Infeld 动力学扇区，其次，证明了初始尺度不变性作用被动态破坏并导致尺度电荷不守恒，尽管仍然存在守恒的膨胀电流。
