Abstract: | A seminar from the Geometric Aspects of Discrete and Ultra-discrete Integrable Systems conference in association with the Newton Institute programme: Discrete Integrable Systems
http://www.gla.ac.uk/departments/mathematics/research/isamp/events/gadudis/programme/ We propose a method to study the integrable cellular automata via the tropical algebraic geometry. First we review the theory of tropical curves and Jacobi varieties introduced by Mikhalkin and Zharkov, and apply it to the spectral curve and the isolevel set of the ultra-discrete Toda lattice (UD-Toda) with periodic boundary condition. Next we introduce the interesting close relation between the periodic UD-Toda and the box and ball system. |
