从su(2)Gaudin模型到可积顶

From su(2) Gaudin Models to Integrable Tops

Matteo Petrera, Orlando Ragnisco

摘要:

在本文中,我们得到了两个著名的刚体动力学的可积情况(拉格朗日顶部和Clebsch系统)进行代数压缩的两体Lax矩阵控制(经典)su(2)Gaudin模型。该程序保留了祖先模型的线性r-矩阵公式。我们给出了所得到的可积系统用su(2)Lax矩阵的Lax表示,该矩阵对谱参数具有有理依赖和椭圆依赖.最后给出了所构造系统的多体扩张的一些结果。

英文摘要:

In the present paper we derive two well-known integrable cases of rigid body dynamics (the Lagrange top and the Clebsch system) performing an algebraic contraction on the two-body Lax matrices governing the (classical) su(2) Gaudin models. The procedure preserves the linear r-matrix formulation of the ancestor models. We give the Lax representation of the resulting integrable systems in terms of su(2) Lax matrices with rational and elliptic dependencies on the spectral parameter. We finally give some results about the many-body extensions of the constructed systems.
