在本文中,我们提出了一个一般的理论框架,从这个框架中可以恢复一些关于孤子存在性和稳定性的已知结果(以及一些新的结果)。给出了孤立波和孤子的抽象定义,建立了一个抽象的存在论。这一理论为克莱恩-戈登方程和规范理论研究孤子的存在性提供了一个强有力的工具。应用这一理论,证明了连续稳定带电q球族的存在性。
In this paper we present a general theoretical framework from which several known results (a some new ones) on the existence and stability of solitons can be recovered.We give an abstract definition of solitary wave and soliton and we develope an abstract existence theory. This theory provides a powerful tool to study the existence of solitons for the Klein–Gordon equations as well as for gauge theories. Applying this theory, we prove the existence of a continuous family of stable charged Q-balls.
