近年来，从弦理论得到暴胀模型的努力是显著的。在研究最充分的情况下，膜暴胀，暴胀阶段通常以相变结束，导致宇宙（超）弦网络的产生。这些弦具有不同于普通宇宙弦的性质，因此为早期宇宙的物理学提供了潜在的探测器。在这封信中，我们回顾了最近的工作在宇宙演化的弦网络。我们讨论了宇宙（超）弦网络的现象学，并得到了膜膨胀模型的约束条件。
There has been notable effort in recent years to obtain inflationary models from string theory. In the most well-studied scenario, brane inflation, the inflationary phase typically ends with a phase transition leading to the production of a network of cosmic (super)strings. These have different properties than ordinary cosmic strings and thus provide a potential probe to the physics of the early universe. In this letter we review recent work on the cosmological evolution of such string networks. Focusing on analytic velocity-dependent evolution models, we discuss the phenomenology of cosmic (super)string networks and obtain constraints for brane-inflation models.
