报告摘要：Self-organized infectious disease patterns have important practical significance for understanding the prevalence and distribution of infectious diseases. Currently, the research on the pattern formations of infectious disease in complex network reaction-diffusion systems is mostly limited to the Turing mechanism, and focuses on the simple reproduction or generation of patterns, and lacks a thorough understanding for the functions and significance of patterns. Combining the linear stability analysis and the variational function theory, we analyzed the dynamic behavior of the conservative complex network reaction-diffusion infectious disease system, determined the border of the spinodal region and the binodal region, and studied the phase separation pattern formations of infectious diseases on typical complex spatial networks. Furthermore, we founded that phase separation patterns can hinder the elimination of infectious diseases.
