Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rational solutions of KP and BKP hierarchies through Toda lattice
户田晶格 KP BKP 层次结构 合理解
2023/4/27
The full Kostant-Toda lattice defined on simple Lie algebras can be viewed as finite version of KP type hierarchies. In this talk I will show you how to explicitly construct (all) rational solutions o...
Old and new reductions of dispersionless Toda hierarchy
dispersionless Toda hierarchy finite-variable reduction waterbag model Landau-Ginzburg potential Lowner equations
2012/6/21
Two types of finite-variable reductions of the dispersionless Toda hierarchy are considered in the geometric perspectives. The reductions are formulated in terms of "Landau-Ginzburg potentials" that p...

We present the general solution to the Plebanski equation for an H-space that admits Killing vectors for an entire SU(2) of symmetries, which is therefore also the general solution of the sDiff(2)Toda...

2009/7/10
对Loop代数L(Dr)上具有长程相互作用的Toda力学系统进行推广,用一组有序整数对(X,Y)来表示Toda链,构造出Loop代数L(Dr)的LaxPair,并给出了系统在(3,2)Toda链情况下的运动方程和Hamiltonian结构.在此模型中,标准的Toda变量之间和附加的坐标变量之间的泊松括号都非零,部分附加的坐标变量之间的泊松结构构成李代数.
研究Loop代数上的一种Toda系统L=[L,M], 其Lax Pair中的M是反对称矩阵,而L=L++M, L+是准上三角矩阵(包含对角部分), 证明这种系统的Lax方程的求解问题与相关的正则Riemann-Hilbert问题等价. 按此方法, 发现在某些特定的初值条件下系统是可积的. 并给出实例求解这一问题, 得到了精确解.
