This chapter is a review of the current understanding of complexity of spiral dynamics from a bifurcation-theor

https://doi.org/10.1007/b102725ever, this naive statement is actually false because, when several species have different diffusion rates, the responses of the antagonistic processes to a local perturbation do not spread at the same rate. As a result, the subtle balance between these processes can break in a nonhomogeneous way. In

We address this issue and show by numerical solutions of deterministic reaction-diffusion equations
