However, to demonstrate the t part is quite difficult in this approach, and it is also hard to employ this method to study hierarchies of non-isospectral evolution equations.作者: 多節(jié) 時(shí)間: 2025-3-22 18:30 作者: 盡管 時(shí)間: 2025-3-22 22:03 作者: 殺人 時(shí)間: 2025-3-23 02:57 作者: 失望昨天 時(shí)間: 2025-3-23 08:30

Multiple Darboux Transformations and Multiple Pole Solutions for AKNS HierarchyUsing a new method—multiple Darboux Transformation method, we gave a set of universal formulas of multiple pole solutions for AKNS hierarchy and its reductions, which include NLS hierarchy and M-KdV hierarchy. In addition, we showed the existance of the bounded multiple pole solutions for NLS hierarchy and M-KdV hierarchy.作者: dowagers-hump 時(shí)間: 2025-3-24 15:54 作者: 小畫像 時(shí)間: 2025-3-24 21:31 作者: 考古學(xué) 時(shí)間: 2025-3-25 00:40
Classical Integrable Systems Generated Through Nonlinearization of Eigenvalue ProblemsIt is a challenge for us to look for new finite-dimensional completely integrable systems. H. Flaschka [l] pointed out an important principle to obtain finite-dimensional integrable systems by constraining infinite-dimensional integrable systems on finite-dimensional invariant subset.作者: Abduct 時(shí)間: 2025-3-25 05:03 作者: Encapsulate 時(shí)間: 2025-3-25 08:04 作者: Mets552 時(shí)間: 2025-3-25 15:37

Zhangju Liu,Min Qianode how responses may demonstrate reasoning about variation. Coding of student responses, according to a spread scale, was reported in Shaughnessy et al. (1999). These hierarchies are describing reasoning in relation to variation, from two perspectives: how students describe the variation and how they attribute cause to variation.作者: Generosity 時(shí)間: 2025-3-26 15:01
