在本文中，我们表明，某些类型的宇宙学膜配置可能会导致拓扑暴胀。在拓扑暴胀的一般模型中，暴胀子场的势有一个严格的界限。简单地说，如果通货膨胀以混合势开始，这些约束似乎可以被消除。然而，由于初始条件的不同，联合收割机拓扑膨胀和混合膨胀很难结合起来。在本文中，我们给出了一些例子，其中使用非常规混合势实现了一种新型的拓扑暴胀。
In this paper we show that certain types of cosmological brane configurations may induce topological inflation. In generic models for topological inflation, there is a strict bound for the potential of the inflaton field. Naively, it seems that these constraints can be removed if inflation starts with a hybrid potential. However, it is difficult to combine topological inflation and hybrid inflation, because of the difference in their initial conditions. In this paper, we show some examples in which a novel type of topological inflation is realized with the unconventional hybrid potential.
