标题： Geometric Construction of non-linear Sigma models with Q-ball/Q-kink solutions

摘要： 涉及U(1)对称性群的非线性Sigma模型使用几何形式主义进行研究。 在这种类型的模型中，找到了Q球和Q-斜角解。 本文描述的几何框架允许识别度量和势能的必要条件，以保证这些Q球和Q-斜角的存在。 使用此过程，已经确定了两种解共存的Sigma模型。 只有内部旋转频率区分将出现哪种缺陷。 显示英文摘要

摘要： Non-linear Sigma models involving U(1) symmetry group are studied using a geometrical formalism. In this type of models, Q-balls and Q-Kinks solutions are found. The geometrical framework described in this article allows the identification of the necessary conditions on the metric and the potential to guarantee the existence of these Q-balls and Q-Kinks. Using this procedure, Sigma models where both types of solutions coexist, have been identified. Only the internal rotational frequency distinguishes which one of these defects will arise.
