title: Kinetics of migration-driven aggregation processes.
abstract: We study the kinetic behavior of the growth of aggregates driven by reversible migration between any two aggregates. For the simple system with the migration rate kernel K(k;j)=K(')(k;j) proportional, variant kj(upsilon) at which the monomers migrate between the aggregates of size k and those of size j, we find that for the upsilon< or =2 case the evolution of the system always obeys a scaling law. Moreover, the typical aggregate size grows as exp(2IA(0)t) in the case of upsilon=2 and as t(1/(2-upsilon)) in the case of -1<upsilon<2. In particular, when upsilon< or =-2, the typical aggregate size always grows as t(1/3) and the aggregate-size distribution approaches a similar scaling form.
