论文摘要
隐藏的对称性为在多场宇宙学模型中找到精确解决方案提供了强大的工具。我们回顾了如何使用这种对称性，可以在两场模型中找到通货膨胀解决方案，从而导致产生原始黑洞。我们还讨论了一个描述暗能量的两场宇宙学模型中的精确解决方案。该解决方案是通过使用隐藏对称性的，尽管后者在标量电势中的恒定项中损坏。以上所有解决方案的特征是磁道空间轨迹迅速转弯。
Hidden symmetries provide a powerful tool for finding exact solutions in multifield cosmological models. We review how, using such symmetries, one can find inflationary solutions in two-field models, which lead to the generation of primordial black holes. We also discuss an exact solution in a two-field cosmological model, which describes dark energy. This solution is obtained with the use of a hidden symmetry, although the latter is broken by a constant term in the scalar potential. All of the above solutions are characterized by field-space trajectories with rapid turns.
