摘要：
We study the stability of the steady state in an aggregation system with injection for one dimension and the mean-field cases. We prove that for any initial perturbation the system is stable and eventually recovers the power-law steady state. The form of the relaxation follows either a stretched exponential (e(-t-alpha), alpha = 2,3) or a power law (t-beta, Beta = 1, 3/4) depending on the type of injection.
