我们研究了（1，1）维时空中由真实的标量场描述的广义模型中缺陷结构的存在。我们使用两种不同的推广：一种是域的函数和它的导数的乘积，另一种是和。我们寻找静态解，并研究相应的线性稳定性的一般理由。我们用几个例子说明了结果，在那里我们找到了稳定的缺陷结构的修改后的配置文件。特别是，我们展示了新的缺陷解决方案可能会引起不存在于更高的空间维度的标准场景中的演变。
We investigate the presence of defect structures in generalized models described by a real scalar field in (1,1) space-time dimensions. We work with two distinct generalizations: one in the form of a product of functions of the field and its derivative, and the other as a sum. We search for static solutions and study the corresponding linear stability on general grounds. We illustrate the results with several examples, where we find stable defect structures of modified profile. In particular, we show how the new defect solutions may give rise to evolutions not present in the standard scenario in higher spatial dimensions.
