对称矩阵包围与可积流体动力链

Symmetric Matrix Ensemble and Integrable Hydrodynamic Chains

Costanza Benassi, Marta Dell'Atti, Antonio Moro

摘要:

对称矩阵包络的配分函数与Pfaff格的一个特解的$τ-$函数一致。我们表明,在偶次幂相互作用的情况下,在热力学极限,$τ-$功能对应于流体动力学类型的可积链的解决方案。我们证明了这样得到的流体动力链是diagonalisable,并承认流体动力减少黎曼不变量在任意数量的组件。

英文摘要:

The partition function of the Symmetric Matrix Ensemble is identified with the $τ-$function of a particular solution of the Pfaff Lattice. We show that in the case of even power interactions, in the thermodynamic limit, the $τ-$function corresponds to the solution of an integrable chain of hydrodynamic type. We prove that the hydrodynamic chain so obtained is diagonalisable and admits hydrodynamic reductions in Riemann invariants in an arbitrary number of components.
