一类新的可积亏损

A new class of integrable defects

E. Corrigan, C. Zambon

摘要:

另一种拉格朗日定义的可积亏损提供和分析。新的方法是足够广泛的,允许描述的缺陷内的Tzitzeica模型,这是不可能在以前的方法,并可能是可推广的。新的,两个参数,正弦戈登缺陷也被描述,它具有类似于一对“融合”缺陷的先前考虑的类型的特性。这些缺陷和Backlund变换之间的关系进行了描述,并提出了一个可积缺陷的哈密顿描述。

英文摘要:

An alternative Lagrangian definition of an integrable defect is provided and analyzed. The new approach is sufficiently broad to allow a description of defects within the Tzitzeica model, which was not possible in previous approaches, and may be generalizable. New, two-parameter, sine-Gordon defects are also described, which have characteristics resembling a pair of 'fused' defects of a previously considered type. The relationship between these defects and Backlund transformations is described and a Hamiltonian description of integrable defects is proposed.
