余代数对称性的(超)可积性:形式及应用

(Super)integrability from coalgebra symmetry: formalism and applications

Angel Ballesteros, Alfonso Blasco, Francisco J. Herranz, Fabio Musso, Orlando Ragnisco

摘要:

回顾了从Poisson余代数构造经典可积系统的余代数方法,强调了辛实现在这一框架中所起的重要作用.给出了许多具有未变形或q-变形余代数对称性的哈密顿算子的例子,并讨论了它们的Liouville超可积性。其中,详细分析了N维非常曲率空间上的(拟极大)超可积系统。进一步推广的余代数方法,利用余代数和循环代数。这种余代数对称性框架推广到量子力学系统是简单的。

英文摘要:

The coalgebra approach to the construction of classical integrable systems from Poisson coalgebras is reviewed, and the essential role played by symplectic realizations in this framework is emphasized. Many examples of Hamiltonians with either undeformed or q-deformed coalgebra symmetry are given, and their Liouville superintegrability is discussed. Among them, (quasi-maximally) superintegrable systems on N-dimensional curved spaces of nonconstant curvature are analysed in detail. Further generalizations of the coalgebra approach that make use of comodule and loop algebras are presented. The generalization of such a coalgebra symmetry framework to quantum mechanical systems is straightforward.
