Abstract:
We study the spike solutions of a reaction diffusion system with cross diffusion terms modelling crime concentration phynomena. The existence of radial symmetric solutions and their linear stabilities are investigated through the study of nonlocal eigenvalue problems. The main difficulty of the problem lies in the strong nonlinearity induced by the nature of the solutons as expressed in the cross diffusion terms.
