“…Now we recall some conclusions about the traveling waves of different dimensional lattice equations with or without delays. In past few years, great progress has been made in the traveling wave solutions for a single equation, see [1], [2], [3], [4], [5], [6], [8], [10], [11], [16], [17], [18], [25], [20], [21], [22], [24], [26], [27], [29] for 1 or 2 dimensional lattices and [19], [23], [28] for higher dimensional lattices. Recently, many authors also paid their attention to the traveling waves for systems with two equations.…”
