Abstract:

We generalize the $\bar{\partial }$-dressing method to investigate a (2+1)-dimensional lattice, which can be regarded as a forced (2+1)-dimensional discrete three-wave equation. The soliton solutions to the (2+1)-dimensional lattice are given through constructing different symmetry conditions. The asymptotic analysis of one-soliton solution is discussed. For the soliton solution, the forces are zero.

Key words: discrete (2 + 1)-dimensional three-wave equation, ∂̄-dressing method, explicit solution
