实周期Sine-Gordon理论中的拓扑现象

Topological Phenomena in the Real Periodic Sine-Gordon Theory

P. G. Grinevich, S. P. Novikov

摘要:

对应于固定谱曲线的实有限间隙Sine-Gordon解的集合由若干连通分量组成。作者最近得到的这些组件的一个简单的明确的描述是用来研究这个属性的后果。特别是这种描述允许计算的拓扑电荷的解决方案(平均的$x$ -衍生物的潜力),并表明,平均的其他标准守恒定律是相同的所有组件。

英文摘要:

The set of real finite-gap Sine-Gordon solutions corresponding to a fixed spectral curve consists of several connected components. A simple explicit description of these components obtained by the authors recently is used to study the consequences of this property. In particular this description allows to calculate the topological charge of solutions (the averaging of the $x$-derivative of the potential) and to show that the averaging of other standard conservation laws is the same for all components.
