论文摘要
我们对多尺度田间手性宇宙学场景的渐近行为进行详细分析。我们介绍了一场,两场和三场手性模型的渐近行为。从这些结果和得出保守的数量中,我们为手性模型的$ n $ fields模型提供了一个定理。我们发现,提供有趣的物理结果的最大标量字段数为两场,而对于$ n> 2 $,新的固定点仅具有数学兴趣,因为它们没有描述与$ n = 2 $恢复的新精确解决方案不同的解决方案。
We perform a detailed analysis for the asymptotic behaviour for the multi-scalar field Chiral cosmological scenario. We present the asymptotic behaviour for the one-field, two-fields and three-fields Chiral models. From these results, and deriving conserved quantities, we present a Theorem for the $N$-fields model for the Chiral model with $N$--fields. We find that the maximum number of scalar fields which provide interesting physical results is two-fields, while for $N>2$ the new stationary points are only of mathematical interest since they do not describe new exact solutions different from those recovered for $N=2$.
