Among the results, we show that perturbation for the nonnegative\r solutions propagates with infinite speed in x1-direction and with finite speed in x2-\r direction if 0 < α < m < p2. We also show that the anisotropic propagation may appear\r when the convection term is weak, backward, or even missing, if 0 < p1 m < p2, p1 1.2009http://hdl.handle.net/20.500.12678/0000000658https://meral.edu.mm/records/658
