Solutions of two-dimensional KISS model (35) on different spatial domain. The initial and parameter values: u0(x, y) = sinc[√(x/π)2 +√ (y/π)2], with D = 1, τ = 0.01, T = 0.5 and α = 2 on a l = 10 and b l = 20. Plots c T = 1.2, l = 10 and d T = 2, l = 20 are obtain with initial data u0(x, y) = cos(x) cos(y) exp(−√(x 22 + y 2 /4))
