Abstract: Starting from the 3-wave interaction equations in 2+1 dimensions (i.e., two space dimensions and one time dimension), we complexify the independent variables, thus doubling the number of real variables, and hence we work in 4+2 dimensions: x1, x2, y1, y2 and t1, t2. In this paper we solve the initial value problem of the 3-wave interaction equations in 4+2 dimensions.
