论文摘要
通常认为，多场理论的Lagrangian包含标量场的动力学术语之和。但是，我们在这里提出了拉格朗日人，其中不包含动力学术语的总和，而是其中的商。有了这种新颖的变化，我们发现通货膨胀宇宙可以用两个标量添加而没有缓慢的近似值来获取。另一方面，也可以通过两个标量来实现恒定的暗能量密度，而无需爱因斯坦宇宙学常数。
It is commonly assumed that the Lagrangian of multi-field theories of gravity contains the sum of kinetic terms of scalar fields. However, we propose here the Lagrangian contains not the sum but the quotient of kinetic terms. With this novel change, we find the inflationary universe can be acquired with two scalars without the slow-roll approximation. On the other hand, a constant dark energy density can also be achieved with two scalars while without the need of Einstein cosmological constant.
