Abstract: Social networks and dynamics has attracted interests of wide range from various areas. There are several important and challenging problems about social networks. The evolution of beliefs or opinions is a fundamental problem in the study of social networks. Here we provide a quite genera sufficient connectivity conditions for the social network to reach an agreement of dispersed beliefs. Another important issue is to locate the source of diffusion, and we establish an approximability of the minimum doubly resolving set problem on general graphs. In addition to the analysis of opinion agreement and opinion source location, opinion intervention is also an important topic to deal with the social crisis and eliminate the psychosocial problem during the opinion evolution. Two new intervention methods are developed to guide crowd or reduce the difference of public opinions.
