英文摘要 | In this paper, we present an efficient numerical scheme to calculate n-periodic wave solutions to the toda-type equations. the starting point is the algebraic condition for having n-periodic wave solutions proposed by akira nakamura. the basic idea is to formulate the condition as a nonlinear least square problem and then use the gauss-newton method to solve it. by use of this numerical scheme, we calculate the 3-periodic wave solutions to some discrete integrable equations such as the toda lattice equation, the lotka-volterra equation, the differential-difference kp equation and so on. |
