论文摘要
我们研究了涉及双曲线空间歧管上的田间双线和指数势的过度通货膨胀模型，从而简要处理了在均匀的双曲线吸引子溶液周围熵和绝热扰动的演变。我们发现，绝热频谱指数将电势的可接受值缩小到很小的区域，严重限制了允许的背景解决方案的状态空间。
We study a Hyperinflation model involving a field doublet on a hyperbolic field-space manifold and an exponential potential, providing a concise treatment of the evolution of the entropic and adiabatic perturbations around the homogeneous hyperbolic attractor solution. We find that the adiabatic spectral index narrows down the admissible values of the potential's slope to a very small region, severely restricting the state space of the allowed background solutions.
