Fields in nonaffine bundles. IV. Harmonious non-Abelian currents in string defects
摘要：
这篇文章继续研究的和谐领域的模型，最近推出的一个著名的谐波类的多标量场在一个支持膜字表在目标空间与弯曲的黎曼度量的动力学非线性推广的类别。像完全和谐的情况下，一个熟悉的例子是由普通正压完美流体，另一个重要的子类是简单的和谐的情况下，它表明，以及“摆动”模式的基础膜世界片，和声音类型的纵向模式，也将有横向振动模式，以光速传播。这种类型的模型所产生的非阿贝尔推广的威滕机制进行字符串形成的普通标量场与一个合适的四次自耦合项的行动。
英文摘要：
This article continues the study of the category of harmonious field models that was recently introduced as a kinetically non-linear generalisation of the well known harmonic category of multiscalar fields over a supporting brane wordsheet in a target space with a curved Riemannian metric. Like the perfectly harmonious case of which a familiar example is provided by ordinary barotropic perfect fluids, another important subcategory is the simply harmonious case, for which it is shown that as well as ``wiggle'' modes of the underlying brane world sheet, and sound type longitudinal modes, there will also be transverse shake modes that propagate at the speed of light. Models of this type are shown to arise from a non-Abelian generalisation of the Witten mechanism for conducting string formation by ordinary scalar fields with a suitable quartic self coupling term in the action.
