Abstract |
We study the interaction of solitons of the ultradiscrete sine-Gordon equation. We give an explicit algorithm which allows one to calculate the asymptotic state of the solitons after interaction, from... their asymptotic state before interaction. This algorithm is formulated in terms of a new entity, which we call `oiston', the origin of which can be traced back to an ultradiscrete version of the discrete KdV equation.show more
