When the space dimension N is equal to three, we show here that (S) has radial solutions with finite mass that blow-up in finite time in a self-similar manner. When N = 2, however, no radial solution with finite mass may give rise to self-similar blow-up.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0377042798001046http://www.sciencedirect.comrestricted access517.956.4539.2Reaction-diffusion systemsblow-upself-similar behaviourmatched asymptotic expansionschemotaxisequationsaggregationclustersmodelEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
