研究了有限维单李代数的Toda场论的离散化问题。定义了晶格上Toda场之间的泊松关系,阐明了晶格Toda场方程的哈密顿结构。我们将Toda场方程转化为τ函数的函数方程,并讨论了它与T系统的对应关系。
The discretization of the Toda field theory for any finite-dimensional simple Lie algebras is studied. We define the Poisson relation among Toda fields on the lattice, and clarify the Hamiltonian structure of the lattice Toda field equation. We transform the Toda field equation into the functional equation of the τ -function, and discuss the correspondence with the T-system.
