Influence of a complex network substrate on reaction–diffusion processes

We discuss recent work on reaction-diffusion processes that take place on complex networks. The inherent inhomogeneity of the substrate leads to a series of new phenomena, which bear only a small resemblance to the classical results of the field. The annihilation rate is abnormally high in such systems, while at the same time depletion zones are absent in the A + A → 0 reaction and no segregation is observed for the A + B → 0 reaction. These results are mainly attributed to the presence of
