Gaudin系统的极限:经典和量子情形

Limits of Gaudin Systems: Classical and Quantum Cases

Alexander Chervov, Gregorio Falqui, Leonid Rybnikov

摘要:

我们考虑具有$N$格位的XXX齐次Gaudin系统,包括经典和量子情形.特别是,我们表明,一个合适的限制程序,让其Lax矩阵的极点碰撞可以用来定义新的家庭的刘维尔积分(在经典的情况下)和新的“高丁”代数(在量子的情况下)。我们将特别讨论总碰撞的情况,这引起了Kapovich和Millson的所谓弯曲流(的推广)。多泊松几何的一些方面将得到解决(在经典的情况下)。我们将利用“Manin矩阵”的性质来提供量子情形下Gaudin代数的显式生成元。

英文摘要:

We consider the XXX homogeneous Gaudin system with $N$ sites, both in classical and the quantum case. In particular we show that a suitable limiting procedure for letting the poles of its Lax matrix collide can be used to define new families of Liouville integrals (in the classical case) and new "Gaudin" algebras (in the quantum case). We will especially treat the case of total collisions, that gives rise to (a generalization of) the so called Bending flows of Kapovich and Millson. Some aspects of multi-Poisson geometry will be addressed (in the classical case). We will make use of properties of "Manin matrices" to provide explicit generators of the Gaudin Algebras in the quantum case.
