摘要:
Hirota bilinear method is proposed to directly construct periodic wave solutions in terms of Riemann theta functions for (2 + 1)-dimensional Toda lattice equations. The asymptotic properties of the periodic waves are analyzed in detail, including one-periodic and two-periodic solutions. Furthermore, the curves of the solutions are plotted to analyze the solutions. It is shown that well-known soliton solutions can be reduced from the periodic wave solutions.
