Abstract | We apply the asymptotic approach for the description of two plane solitons interacting under an angle to each other in 2D Toda lattices with the quadratic or triangle/hexagonal structure. We demonstrate the influence of lattice anisotropy on dispersion relations and soliton structures. With the help of the asymptotic approach, we study soliton interactions in the long-wave approximation and show that it is possible to find the spatial phase shifts experienced by each soliton due to the interaction with its counterpart. In contrast to earlier studied soliton interactions within the quasi-one-dimensional equations, here we consider a fully two-dimensional arrangement with an arbitrary angle between soliton fronts. |
