We consider the effects of migration on intraguild predation (IGP) via lattice models and pair approximation. The following results can be found: there exists asymmetry between two consumers’ migration effects on the spatial structure of IGP; migration of each consumer reduces its own clumping...

In this paper, we introduce a non-interacting boson model to investigate the topological structure of complex networks. By exactly solving this model, we show that it provides a powerful analytical tool in uncovering the important properties of realistic networks. We find that the ground-state...

The industry transfer from east region to west region of China has become an inevitable trend of economic development, it need massive agricultural population change to non-agricultural population in China. Based on the redefinition of the citizenization of migrant workers, this article points...
