Title: Ultradiscrete Analysis of Nonlinear Systems
Time: 2007-12-27 (Thu.)  15:00-16:00
Abstract: Ultradiscrete equations are obtained by a limiting procedure from discrete equations in a way that allow both dependent and independent variables to take only discrete values. We have shown that many of soliton equations have their ultradiscrete analogues which admit the same kind of soliton solutions. In this talk, we first explain how the ultradiscretization procedure works on soliton equations and then discuss about applications of the procedure to a few nonlinear systems.
