| Outline of Final Research Achievements |
We analyzed the mechanism of the species localization in reaction-diffusion networks. We proved analytically that uniform distribution of species becomes unstable when a model parameter exceeds a certain threshold. Numerical results suggest that stationary particle-like structures (spots) develop spontaneously after the instability. We also found numerically that the stationary spot becomes unstable after another instability, which leads the onset of translational motion of the spot. After this instability, the spot moves over the entire network.
