Outline of Final Research Achievements |
The purpose of this research is construction of ultradiscrete integrable system. Ultradiscrete equations consist of addition, subtraction and max operation. In particular, I focused on ultradiscrete soliton system. This system is derived from discrete soliton system by a limiting procedure called ultradiscretization. In this research, I gave a new ultradiscrete equation called ultradiscrete Periodic Phase soliton equation and its discrete analogue. These equations have extended soliton solutions called ultradsicrete or discrete Periodic Phase Soliton solution respectively. An ultradiscrete soliton equation which has two different ultradiscrete soliton solutions was also given. It is expected that these solutions may be clues for construction of ultradiscrete integrable system.
