Möbius Symmetry of Discrete Time Soliton Equations
Jun-ichi Yamamoto
We have proposed, in our previous papers, a method to characterize integrable discrete soliton equations. In this paper we generalize the method further and obtain a -difference…
Nambu system associated with n-dimensional maps
J. Yamamoto
We studied that arbitrary 2-dimensional maps are Hamilton system if a initial value of map is a "time" variable. In this paper, we generalize this correspondence, and show that an…
A Characterization of Discrete Time Soliton Equations
Satoru Saito, Noriko Saitoh, Jun-ichi Yamamoto +1
We propose a method to characterize discrete time evolution equations, which generalize discrete time soliton equations, including the -difference Painlevé IV equations discusse…
A Hamiltonian Flows Associated with Two Dimensional Map
Satoru Saito, Akira Shudo, Jun-ichi Yamamoto +1
For a given differentiable map , which has an inverse, we show that there exists a Hamiltonian flow in which x plays the role of the time variable while y…
