具有局域峰势模型中（2+1）维孤子结构的宇宙学形成
Cosmological Formation of (2+1)-Dimensional Soliton Structures in Models Possessing Potentials with Local Peaks
摘要：
研究了两个实标量场和至少有一个鞍点和一个局部极大值的势场模型中畴壁和类弦孤子的产生。该模型被视为三维整体结构的二维空间切片。结果表明，在早期宇宙中，这两种类型的孤子可能会出现。此外，定性估计的畴壁和字符串的形成概率。结果发现，与畴壁相比，形成弦状孤子的几率被抑制。
英文摘要：
Production of domain walls and string-like solitons in the model with two real scalar fields and potential with at least one saddle point and a local maximum is considered. The model is regarded as 2-dimensional spatial slices of 3-dimensional entire structures. It is shown that, in the early Universe, both types of solitons may appear. In addition, the qualitative estimate of the domain walls and strings formation probabilities is presented. It is found that the probability of the formation of string-like solitons is suppressed compared to that of domain walls.
